MindSpore 1.10.0 Release Notes

Major Features and Improvements

DataSet

  • [STABLE]The timeout waiting time is adjusted in data sinking mode. The default value is 600s after adjusted. This solves the isuses that the GetNext operator may timeout due to environment resource competition and large computing workload when training in sink mode.

Bug fixes

  • Fixed an issue where some Primitive operators in AMP cannot be instantiated in graph mode and the interface is unavailable.
  • Fixed an issue of DynamicRNN execution failure in LSTM network under the scenario of computational force segmentation on Ascend platform.
  • Fixed DEVICE_ID cannot be set by single card train scripts parameters in mobilenet, fasterrcnn, yolo, etc.

API Change

Backwards Incompatible Change

Python API
mindspore.dataset.MindDataset interface changes input parameter dataset_file(!27542:dataset: change dataset_file into dataset_files for MindDataset)

MindDataset contains the input parameter dataset_file, which is in the singular format. It can receive a single file path or a list that stores multiple file paths. Thus It is preferred to change the input parameter dataset_file into plural format. In addition, the input parameters of most dataset API, such as TFRecordDataset, are in plural formart (dataset_files). To ensure consistency, the input parameter dataset_file of MindDataset is changed to plural formart as dataset_files, we can see the updated version in api of mindspore.dataset.MindDataset.

Delete mindspore.Tensor's property virtual_flag(!26989:change tensor.virtual_flag and parameter.is_init interfaces to inner api)
Delete mindspore.Parameter's property is_init(!26989:change tensor.virtual_flag and parameter.is_init interfaces to inner api)
Delete mindspore.nn.ROC's interface roc(!25713:ROC.roc change to inner api)
The shard() interface of primitive is changed from shard(strategy) to shard(in_strategy=None, out_strategy=None)
The set_auto_parallel_context() interface of context is changed from
set_auto_parallel_context(parallel_mode=AUTO_PARALLEL, auto_parallel_search_mode="dynamic_programming") to set_auto_parallel_context(parallel_mode=AUTO_PARALLEL, search_mode="dynamic_programming")

Collect Data and Create Landscape

Python API
mindspore.train.callback.SummaryCollector interface's parameter collect_specified_data add new operations collect_landscape (!26229:add loss landscape visualization function)

collect_landscape can collect the parameters needed to create the loss landscape. we can see the updated version in api of mindspore.train.callback.SummaryCollector.

mindspore.train.callback add new interface SummaryLandscape (!26229:add loss landscape visualization function)

SummaryLandscape can help you to collect loss landscape information. It can create landscape in PCA direction or random direction by calculating loss. We can see the updated version in api of mindspore.train.callback.SummaryLandscape.

mindspore.dataset.Dataset.device_que interface removes unused parameter prefetch_size(!18973:Delete unused param in device_que)

Previously, we have a parameter prefetch_size in device_que to define the prefetch number of records ahead of the user's request. But indeed this parameter is never used which means it is an ineffective parameter. Therefore, we remove this parameter in 1.3.0 and users can set this configuration by mindspore.dataset.config.set_prefetch_size.

LiteSession liteSession = new LiteSession();
boolean ret = liteSession.init(config);
if (!ret) {
  // handle init LiteSession failed ...
}

now we can create a LiteSession object with new API just like:

MSConfig config;
// config options ...
LiteSession liteSession = createSession(config);
if (liteSession == null) {
  // handle create LiteSession failed ...
}
new static method for creating LiteSession byModelBuffer and MSConfig in LiteSession.class

Previously, if we want to inference a model, we need to call APIs like:

MSConfig config;
// config options ...
LiteSession liteSession = new LiteSession();
boolean initSessionRet = liteSession.init(config);
if (!initSessionRet) {
  // handle init LiteSession failed and return ...
}
Model model = new Model();
boolean loadModelRet = model.loadModel(modelMappedByteBuffer);
if (!loadModelRet) {
  // handle load model failed and return ...
}
boolean compileModelRet = liteSession.compileGraph(model);
if (!loadModelRet) {
  // handle compile model failed and return ...
}
model.free();
// liteSession is ready to inference model, call runGraph in LiteSession.class ...

now we can use new API just like:

MSConfig config;
// config options ...
LiteSession liteSession = createSession(modelMappedByteBuffer, config);
if (liteSession == null) {
  // handle init LiteSession failed and return ...
}
// liteSession is ready to inference model, call runGraph in LiteSession.class ...

New createSession method is an API that integrates four old APIs: LiteSession.init, Model.loadModel, LiteSession.compileGraph and model.free. It is simple and efficient as it reduces one modelBuffer copy operation.

new methods getFeaturesMap and updateFeatures for in LiteSession.class

Recently, we add a new C++ api in LiteSession class, Correspondingly we add a new java API in LiteSession.java.

public List<MSTensor> getFeaturesMap() {
         List<Long> ret = this.getFeaturesMap(this.sessionPtr);
                ArrayList<MSTensor> tensors = new ArrayList<MSTensor>();
                for (Long msTensorAddr : ret) {
                    MSTensor msTensor = new MSTensor(msTensorAddr);
                    tensors.add(msTensor);
                }
                return tensors;
   }
   public boolean updateFeatures(List<MSTensor> features) {
            long[] inputsArray = new long[features.size()];
            for (int i = 0; i < features.size(); i++) {
                inputsArray[i] = features.get(i).getMSTensorPtr();
            }
             return this.updateFeatures(this.sessionPtr, inputsArray);
   }
new methods export to replace saveToFile API in LiteSession.class

Recently, we add a new C++ api in LiteSession class, Correspondingly we add a new java API in LiteSession.java.

public boolean export(String modelFileName, int modelType, int quantizationType) {
        return this.export(this.sessionPtr, modelFileName, modelType, quantizationType);
    }
new train related API moved to LiteSession.class from TrainSession.class

Align with update of C++ api in LiteSession class, add new java API to LiteSession.java Correspondingly.

public class LiteSession {
...
public static LiteSession createTrainSession(String modelName, final MSConfig config, boolean trainMode){...}
public boolean train() {...}
public boolean eval() {...}
...

Python API
mindspore.numpy.array(), mindspore.numpy.asarray(), mindspore.numpy.asfarray(), mindspore.numpy.copy() now support GRAPH mode, but cannot accept numpy.ndarray as input arguments anymore(!12726:Add March Numpy interfaces to mindspore)

Previously, these interfaces can accept numpy.ndarray as arguments and convert numpy.ndarray to Tensor, but cannot be used in GRAPH mode.
However, currently MindSpore Parser cannot parse numpy.ndarray in JIT-graph. To support these interfaces in graph mode, we have to remove numpy.ndarray support. With that being said, users can still use Tensor to convert numpy.ndarray to tensors.

1.1.1 1.2.0
>>> import mindspore.numpy as mnp
>>> import numpy
>>>
>>> nd_array = numpy.array([1,2,3])
>>> tensor = mnp.asarray(nd_array) # this line cannot be parsed in GRAPH mode
>>> import mindspore.numpy as mnp
>>> import numpy
>>>
>>> tensor = mnp.asarray([1,2,3]) # this line can be parsed in GRAPH mode
mindspore.numpy interfaces remove support for keyword arguments out and where(!12726:Add March Numpy interfaces to mindspore)

Previously, we have incomplete support for keyword arguments out and where in mindspore.numpy interfaces, however, the out argument is only functional when where argument is also provided, and out cannot be used to pass reference to numpy functions. Therefore, we have removed these two arguments to avoid any confusion users may have. Their original functionality can be found in np.where

1.1.1 1.2.0
>>> import mindspore.numpy as np
>>>
>>> a = np.ones((3,3))
>>> b = np.ones((3,3))
>>> out = np.zeros((3,3))
>>> where = np.asarray([[True, False, True],[False, False, True],[True, True, True]])
>>> res = np.add(a, b, out=out, where=where) # `out` cannot be used as a reference, therefore it is misleading
>>> import mindspore.numpy as np
>>>
>>> a = np.ones((3,3))
>>> b = np.ones((3,3))
>>> out = np.zeros((3,3))
>>> where = np.asarray([[True, False, True],[False, False, True],[True, True, True]])
>>> res = np.add(a, b)
>>> out = np.where(where, x=res, y=out) # instead of np.add(a, b, out=out, where=where)
Turn ops.MakeRefKey into an internal interface (!12010:Convert MakeRefKey to an internal interface)

Previously MakeRefKey is an external interface that is not used, now make it an internal interface with the same usage. We do not recommend users to use this interface, and we will remove the relevant introduction of this interface from the official website.

ops.ApplyFtrl, ops.ApplyMomentum, ops.ApplyRMSProp, ops.ApplyCenteredRMSProp change the output on Ascend backend from multiple to a single. (!11895:unify mindir for different backend: the output num of optimizer ops, the backward of concat)

Previously the number of outputs of these operator is different on different backends. To unify their definition we change their output on Ascend backend from multiple to a single.

P.FusedBatchNorm, P.FusedBatchNormEx deleted (!12115:IR operators of GPU and CPU are unified as batchnorm)

The FusedBatchNorm and FusedBatchNormEx interface has been deleted. Please use the batchnorm operator to replace it.

MetaTensor deleted (!10325:modify MetaTensor and Tensor)

The MetaTensor interface has been deleted. The function of MetaTensor has been integrated into tensor.

ControlDepend is deleted, use Depend instead. The decorator @C.add_flags(has_effect=True) does not work. (!13793:remove control_depend from py file)

Previously, we used ControlDepend to control the execution order of multiple operators. In version 1.2.0, mindspore introduces the auto-monad side effects expression to ensure that the perform order of user's semantics is correct. Therefore, ControlDepend is deleted and Depend is recommended.

In most scenarios, if operators have IO side effects (such as print) or memory side effects (such as assign), they will be executed according to the user's semantics. In some scenarios, if the two operators A and B have no order dependency, and A must be executed before B, we recommend using Depend to specify their execution order. See the API documentation of the Depend operator for specific usage.

1.1.1 1.2.0
    In some side-effect scenarios, we need to ensure the execution order of operators.
    In order to ensure that operator A is executed before operator B, it is recommended
    to insert the Depend operator between operators A and B.

    Previously, the ControlDepend operator was used to control the execution order.
    Since the ControlDepend operator is deprecated from version 1.1, it is recommended
    to use the Depend operator instead. The replacement method is as follows::

        a = A(x)                --->        a = A(x)
        b = B(y)                --->        y = Depend(y, a)
        ControlDepend(a, b)     --->        b = B(y)
    In most scenarios, if operators have IO side effects or memory side effects,
    they will be executed according to the user's semantics. In some scenarios,
    if the two operators A and B have no order dependency, and A must be executed
    before B, we recommend using Depend to specify their execution order. The
    usage method is as follows::

        a = A(x)                --->        a = A(x)
        b = B(y)                --->        y = Depend(y, a)
                                --->        b = B(y)

After the introduction of the auto-monad side effect expression feature, the decorator @C.add_flags(has_effect=True) does not work. If the decorator is used in the script, please modify. Take the overflow identification operator (without side effects) as an example, the modification method is as follows:

1.1.1 1.2.0
@C.add_flags(has_effect=True)
def construct(self, *inputs):
    ...
    loss = self.network(*inputs)
    init = self.allo_status()
    self.clear_status(init)
    ...
def construct(self, *inputs):
    ...
    loss = self.network(*inputs)
    init = self.allo_status()
    init = F.depend(init, loss)
    clear_status = self.clear_status(init)
    ...
C++ API
C++ API support dual ABI now.(!12432:api support dual abi )

1.1.1 supports only the old ABI. Currently, both the new and the old are supported.

1.1.1 1.2.0
add_compile_definitions(_GLIBCXX_USE_CXX11_ABI=0)
add_compile_definitions(_GLIBCXX_USE_CXX11_ABI=0)  # old ABI are supported
add_compile_definitions(_GLIBCXX_USE_CXX11_ABI=1)  # new ABI are supprrted, too
                                                   # write nothing, use new ABI as default
Context refactor.(!13515:cpp api modify)

The Context class is refactored. For details, see the API docs.

1.1.1 1.2.0
GlobalContext::SetGlobalDeviceTarget(kDeviceTypeAscend310);       // set device target is ascend310
GlobalContext::SetGlobalDeviceID(0);                              // set device id is 0
auto model_context = std::make_shared<ModelContext>();            // create a model context
ModelContext::SetInsertOpConfigPath(model_context, "./aipp.cfg")  // set aipp config file is ./aipp.cfg
auto model_context = std::make_shared<Context>();                 // create a model context
auto ascend310_info = std::make_shared<Ascend310DeviceInfo>();
model_context.MutableDeviceInfo().push_back(ascend310_info );     // set device target is ascend310
ascend310_info->SetDeviceID(0);                                   // set device id is 0
ascend310_info->SetInsertOpConfigPath("./aipp.cfg");              // set aipp config file is ./aipp.cfg
LoadModel interface changes.(!13515:cpp api modify)

LoadModel is renamed Load. No exception is thrown new but the return status should be checked.

1.1.1 1.2.0
try {
  auto graph = Serialization::LoadModel(model_file_path, kMindIR);
} catch (...) { ... }
Graph graph;
auto ret = Serialization::Load(model_file_path, kMindIR, &graph);
if (ret != kSuccess) { ... }
Model ctor changes.(!13515:cpp api modify)

Model uses a non-parameter ctor now, and arguments are passed in through Build.

1.1.1 1.2.0
Model net(net_cell, model_context);
auto ret = net.Build();
if (ret != kSuccess) { ... }
Model net;
auto ret = net.Build(net_cell, model_context);
if (ret != kSuccess) { ... }
MSTensor::CreateTensor returns a native pointer now.(!13515:cpp api modify)

MSTensor::CreateTensor and MSTensor::CreateRefTensor returns a native pointer now, need to be destroy by DestroyTensorPtr.

1.1.1 1.2.0
auto tensor = MSTensor::CreateTensor(xxx, xxx, ...);
auto name = tensor.Name();
auto tensor = MSTensor::CreateTensor(xxx, xxx, ...);
auto name = tensor->Name();
MSTensor::DestroyTensorPtr(tensor);

All operators are supported in GPU.

Deprecations

Python API
nn.MatMul is now deprecated in favor of ops.matmul (!12817:numpy-native deprecate nn.MatMul)

ops.matmul follows the API of numpy.matmul as closely as possible. As a function interface, ops.matmul is applied without instantiation, as opposed to nn.MatMul, which should only be used as a class instance.

1.1.1 1.2.0
>>> import numpy as np
>>> from mindspore import Tensor, nn
>>>
>>> x = Tensor(np.ones((2, 3)).astype(onp.float32)
>>> y = Tensor(np.ones((3, 4)).astype(onp.float32)
>>> nn.MatMul()(x, y)
>>> import numpy as np
>>> from mindspore import Tensor, ops
>>>
>>> x = Tensor(np.ones((2, 3)).astype(onp.float32)
>>> y = Tensor(np.ones((3, 4)).astype(onp.float32)
>>> ops.matmul(x, y)

API Change

API Incompatible Change

C++ API
Add header file named lite_types.h for some common data structs. (!12262:[MS][LITE][Develop]remove cross dependency in inner headers)

Previously, some common data structs such as CpuBindMode and DeviceType are in context.h, this may cause cross-dependency between headers. So we create a new header named lite_types.h for some common data structs and move CpuBindMode and DeviceType from context.h into lite_types.h.

lite_types.h
namespace mindspore::lite {
/// \brief CpuBindMode defined for holding bind cpu strategy argument.
typedef enum {
  NO_BIND,    /**< no bind */
  HIGHER_CPU, /**< bind higher cpu first */
  MID_CPU     /**< bind middle cpu first */
} CpuBindMode;

/// \brief DeviceType defined for holding user's preferred backend.
typedef enum {
  DT_CPU, /**< CPU device type */
  DT_GPU, /**< GPU device type */
  DT_NPU  /**< NPU device type */
} DeviceType;
}  // namespace mindspore::lite
Add some new interfaces in ms_tensor.h for unified runtime API.(!13515:cpp api modify)

Previously, users could not create MSTensor or modify ``MSTensor, all MSTensor are created and managed by framework. However users need to create or modify MSTensor sometimes such as pre-processing input data. So we provide two new interfaces in ms_tensor.h: `CreateTensor` interface for creating `MSTensor` by user and `set_shape` interface for modifying the shape of `MSTensor`.

CreateTensor
/// \brief Create a MSTensor.
///
/// \return Pointer to an instance of MindSpore Lite MSTensor.
static MSTensor *CreateTensor(const std::string &name, TypeId type, const std::vector<int> &shape, const void *data,
                                size_t data_len);
set_shape
/// \brief Set the shape of MSTensor.
virtual void set_shape(const std::vector<int> &shape) = 0;

Previously, users could access to data of MSTensor by interface named MutableData. However MutableData is not only returning data of tensor but also allocating data for tensor if its data is nullptr. So we provide a new interfaces in ms_tensor.h named data for returning data of tensor without allocating automatically.

data
/// \brief Get the pointer of data in MSTensor.
///
/// \note The data pointer can be used to both write and read data in MSTensor. No memory buffer will be
/// allocated.
///
/// \return the pointer points to data in MSTensor.
virtual void *data() = 0;
Delete DimensionSize() in ms_tensor.h.(!13515:cpp api modify)

The interface named DimensionSize is fuinctionally overlapped with the interface named shape. For the simplicity of the interface, we delete DimensionSize and recommend users to use the new interface named shape instead.

DimensionSize()
/// \brief Get size of the dimension of the MindSpore Lite MSTensor index by the parameter index.
///
/// \param[in] index Define index of dimension returned.
///

Move allocator from namespace mindspore::lite to namespace lite for unified runtime API.(!13515:cpp api modify)

Previously, class Allocator is in namespace mindspore::lite. Considering unified allocator interface for unified runtime API, we move Allocator to namespace mindspore.

1.1.0 1.2.0
namespace mindspore::lite {
/// \brief Allocator defined a memory pool for malloc memory and free memory dynamically.
///
/// \note List public class and interface for reference.
class Allocator;
}
namespace mindspore {
/// \brief Allocator defined a memory pool for malloc memory and free memory dynamically.
///
/// \note List public class and interface for reference.
class Allocator;
}
