Whe 1. The MindSpore operator is used in data processing. Multi-threaded/multi-process is usually in the data processing process, so there is a limitation of using MindSpore operators in this scenario. It is recommended to use a three-party implementation instead of the operator use in the data processing process, such as numpy, opencv, pandas, PIL. 2. Control flow. For details, refer to [Flow Control Statements](https://www.mindspore.cn/tutorials/experts/en/r1.9/network/control_flow.html). Compilation in graph mode can be slow when multiple layers of conditional control statements are called. -3. Slicing operation. When it comes to slicing a Tesnor, note that whether subscript of the slice is a variable. When it is a variable, there will be restrictions.

When it is a variable, there will be restrictions. Please refer to network body and loss building for dynamic shape mitigation. 4. Customized mixed precision conflicts with `amp_level` in Model, so don't set `amp_level` in Model if you use customized mixed precision. 5. In Ascend environment, Conv, Sort and TopK can only be float16, and add [loss scale](https://mindspore.cn/tutorials/experts/en/r1.9/others/mixed_precision.html) to avoid overflow. 6. In the Ascend environment, operators with the stride property such as Conv and Pooling have rules about the length of the stride, which needs to be mitigated. diff --git a/docs/mindspore/source_zh_cn/migration_guide/analysis_and_preparation.md b/docs/mindspore/source_zh_cn/migration_guide/analysis_and_preparation.md index 6a55c58c55..3419213ec6 100644 --- a/docs/mindspore/source_zh_cn/migration_guide/analysis_and_preparation.md +++ b/docs/mindspore/source_zh_cn/migration_guide/analysis_and_preparation.md @@ -331,7 +331,7 @@ MindSpore在持续交付中，部分功能存在限制，在网络迁移过程 想要了解动态shape，需要先了解什么是静态shape。 静态shape指在网路执行阶段Tensor的shape没有发生变化。 -比如resnet50网络如果保证图片的输入shape一直是`224*224`的，那么在网络训练阶段，四个残差模块的输出Tesnor的shape分别是`B*64*56*56`，`B*128*28*28`，`B*256*14*14`，`B*512*7*7`，`B`指`BatchSize`，在训练过程中也是固定的，此时网络中全部是静态的shape，没有动态shape。 +比如resnet50网络如果保证图片的输入shape一直是`224*224`的，那么在网络训练阶段，四个残差模块的输出Tensor的shape分别是`B*64*56*56`，`B*128*28*28`，`B*256*14*14`，`B*512*7*7`，`B`指`BatchSize`，在训练过程中也是固定的，此时网络中全部是静态的shape，没有动态shape。 如果输入的shape不一定是`224*224`的，那么四个残差模块输出Tensor的shape将会随输入shape变化，此时就不是静态shape，而是动态shape了。一般动态shape引入的原因有： #### 输入shape不固定 diff --git a/docs/mindspore/source_zh_cn/migration_guide/model_development/model_development.md b/docs/mindspore/source_zh_cn/migration_guide/model_development/model_development.md index b8d24b4736..53af31d61a 100644 --- a/docs/mindspore/source_zh_cn/migration_guide/model_development/model_development.md +++ b/docs/mindspore/source_zh_cn/migration_guide/model_development/model_development.md @@ -58,7 +58,7 @@ 1. 数据处理中使用MindSpore的算子。数据处理过程一般会有多线程/多进程，此场景下数据处理使用MindSpore的算子存在限制，数据处理过程中使用的算子建议使用三方的实现代替，如numpy，opencv，pandas，PIL等。 2. 控制流。详情请参考[流程控制语句](https://www.mindspore.cn/tutorials/experts/zh-CN/r1.9/network/control_flow.html)。当多层调用条件控制语句时在图模式下编译会很慢。 -3. 切片操作，当遇到对一个Tesnor进行切片时需要注意，切片的下标是否是变量，当是变量时会有限制，请参考[网络主体和loss搭建](https://www.mindspore.cn/docs/zh-CN/r1.9/migration_guide/model_development/model_and_loss.html)对动态shape规避。 +3. 切片操作，当遇到对一个Tensor进行切片时需要注意，切片的下标是否是变量，当是变量时会有限制，请参考[网络主体和loss搭建](https://www.mindspore.cn/docs/zh-CN/r1.9/migration_guide/model_development/model_and_loss.html)对动态shape规避。 4. 自定义混合精度和Model里的`amp_level`冲突，使用自定义的混合精度就不要设置Model里的`amp_level`。 5. 在Ascend环境下Conv，Sort，TopK只能是float16的，注意加[loss scale](https://mindspore.cn/tutorials/experts/zh-CN/r1.9/others/mixed_precision.html)避免溢出。 6. 在Ascend环境下Conv，Pooling等带有stride属性的算子对stride的长度有规定，需要规避。 -- Gitee
