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

mindspore_lite whl: mindspore_lite-2.2.0-cp37-cp37m-linux_x86_64.whl
mindspore_lite tar.gz: mindspore-lite-2.2.0-linux-x64.tar.gz

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:

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
Find and move to the mindspore_lite installation path, like /your_path_to/mindspore-lite
Run command find ./ -name libascend_kernel_plugin.so to find the so file, and you will get the following path:

Q7 Problems related to model converting

SetGraphInputShape] Failed to find input xxx in input_shape yyy:xxxxxxxxxxx occurs when converting model to Device-side mindir by converter_lite. If you convert dbnet_resnet50.mindir to Device-side mindir with the config.txt as following:

[ascend_context]
input_format=NCHW
input_shape=args0:[1,3,736,1280]

and run the following command to convert model:

converter_lite --saveType=MINDIR --fmk=MINDIR --optimize=ascend_oriented --modelFile=dbnet_resnet50.mindir --outputFile=dbnet_resnet50_lite --configFile=config.txt

RuntimeError: build_from_file failed! Error is Common error code.

Reason:

Cloud-Side mindir model should convert to Device-Side mindir model first.
Mismatch version of converter_lite tool and mindspore_lite. For example, it may fail when using converter_lite 2.2 to get Device-Side mindir, and do inference with mindspore_lite 2.1.

Q8 Problems related to inference

When doing inference with deploy/py_infer/infer.py, it may occur TypeError: unhashable type: 'numpy.ndarray'

TypeError: unhashable type: 'numpy.ndarray'

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

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:

...
train:
  ckpt_save_dir: './tmp_det'
  dataset_sink_mode: True
  dataset:
    type: DetDataset
    dataset_root: /data/ocr_datasets
    data_dir: ic15/det/train/ch4_training_images
    label_file: ic15/det/train/det_gt.txt
    sample_ratio: 1.0
    use_minddata: True                          <-- Set this configuration
...
eval:
  ckpt_load_path: tmp_det/best.ckpt
  dataset_sink_mode: False
  dataset:
    type: DetDataset
    dataset_root: /data/ocr_datasets
    data_dir: ic15/det/test/ch4_test_images
    label_file: ic15/det/test/det_gt.txt
    sample_ratio: 1.0
    use_minddata: True                          <-- Set this configuration
...

Try to set the train.loader.num_workers in the configuration file to a larger value to enhance the number of threads fetching dataset if the training server has enough CPU cores:

...
train:
  ...
  loader:
    shuffle: True
    batch_size: 10
    drop_remainder: True
    num_workers: 12                             <-- Set this configuration
...

Q10 Error about `libgomp-d22c30c5.so.1.0.0`

The following error may occur when running mindocr

You can try the following steps to fix it:

search libgomp-d22c30c5.so.1.0.0 in your python install path

cd /root/mindocr_env/lib/python3.8
find ~ -name libgomp-d22c30c5.so.1.0.0

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:

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)
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.
cd lanms-1.0.2
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
run python setup.py install and completely install lanms.
