The problems occur due to the mismatch of mindspore python whl package, mindspore_lite python whl package andmindspore_lite tar package. Please check the following items according MindSpore download and MindSpore Lite download:

  • Consistent version of mindspore, mindspore_lite, e.g. 2.2.0
  • Consistent version of mindspore_lite whl and mindspore_lite tar package, e.g. 2.2.0
  • Both mindspore_lite whl package and mindspore_lite tar package are Cloud-side

For example, the following combination of packages is suitable when the platform is linux x86_64 with Ascend

This problem occur when libascend_kernel plugin.so is not successfully added to environment variables(LD_LIBRARY_PATH), which contained in mindspore_lite tar package. The solution is as follows:

  1. Check mindspore_lite tar package has been installed. If not, please follow the MindSpore Lite download, install tar package and whl package. Please make sure the packages are Clound-side and support Ascend platform. See MindSpore download for details

  2. Find and move to the mindspore_lite installation path, like /your_path_to/mindspore-lite

  3. Run command find ./ -name libascend_kernel_plugin.so to find the so file, and you will get the following path:

./runtime/lib/libascend_kernel_plugin.so
  1. Add the path to to environment variables:

This problem occurs due to shape error, please check:

  • Use suitable model. For example, it may fail and pass detection model to --rec_model_path parameter.
  • Use inference model(not training model) to do converting.

Q9 Training speed of DBNet not as fast as expexted

When traning DBNet series networks (including DBNet MobileNetV3, DBNet ResNet-18, DBNet ResNet-50, and DBNet++ ResNet-50) using following command, the training speed is not as fast as expexted. For instance, the training speed of DBNet MobileNetV3 can reach only 80fps which is slower than the expecting 100fps.

python tools/train.py -c configs/det/dbnet/db_mobilenetv3_icdar15.yaml

This problem is due to the complex data pre-processing procedures of DBNet. The data pre-processing procedures will become the performance bottleneck if the computation ability of a CPU core of the training server is relatively weak.

Solutions

  1. Try to set the train.dataset.use_minddata and eval.dataset.use_minddata in the configuration file to True. MindOCR will execute parts of data pre-processing procedures using MindSporeMindData:

Q14 Failed to install lanms

The following error occur when installing lanms 

ImportError: Python version mismatch: module was compiled for version 3.8, while the interpreter is running version 3.7.
Some Python 3.7 environment may meet this problem when multiple python3 environment exists. You could try the following steps to solve this problem: 1. run pip3 install lanms -i https://pypi.tuna.tsinghua.edu.cn/simple, and get the url for downloading lanms-1.0.2.tar.gz(like https://pypi.tuna.tsinghua.edu.cn/packages/96/c0/50dc2c857ed060e907adaef31184413a7706e475c322236d346382e45195/lanms-1.0.2.tar.gz) 2. use this url and dowload the lanms-1.0.2.tar.gz, run tar -zxvf lanms-1.0.2.tar.gz to decompress the package. 3. cd lanms-1.0.2 4. edit the Makefile, replace python3-config with python3.7-config in line 1 and line 2, and you could get 
CXXFLAGS = -I include  -std=c++11 -O3 $(shell python3.7-config --cflags)
LDFLAGS = $(shell python3.7-config --ldflags)
...
save Makefile. So that the make process would exactly compile with python3.7 environment 5. run python setup.py install and completely install lanms.
