I have installed OpenVINO for CVAT on Mac, but some problem with 'libcpu_extension_avx2.so'.
- OS : macOS Catalina 10.15.1
- OpenVINO : 2020.1.023
When executing the 'Auto Segmentation' function or click 'Submit' button after all necessary files attached in 'Upload a new model' page, the following error occurs.
Cannot load library '/opt/intel/openvino_2020.1.023/deployment_tools/inference_engine/lib/intel64/libcpu_extension_avx2.so': /opt/intel/openvino_2020.1.023/deployment_tools/inference_engine/lib/intel64/libcpu_extension_avx2.so: cannot open shared object file: No such file or directory '
There is no 'libcpu_extension_avx2.so' file in the path '/opt/intel/openvino_2020.1.023/deployment_tools/inference_engine/lib/intel64/' in my Mac.
How can I get the 'libcpu_extension_avx2.so' file?
I want to solve the error.
Unfortunately, as one of backward incompatible changes compared with OpenVINO toolkit 2019 R3 build, the CPU extensions library libcpu_extension_avx2.so was removed in 2020.1 build, so the extensions were moved into the plugin.
You could try OpenVINO toolkit 2019 R3 build.
Best regards, Max.
Where to get the libcpu_extension_avx2.so. Could you please elaborate?

Hello, Artem, Rachel.
In OpenVINO toolkit 2020.1 build CPU extensions (including AVX) have been included into CPU MKL-DNN plugin - https://docs.openvinotoolkit.org/latest/_docs_IE_DG_supported_plugins_CPU.html
The plugin file libMKLDNNPlugin.so is located in the same directory: openvino/deployment_tools/inference_engine/lib/intel64/
If you see any errors related to missing libcpu_extension_avx2.so file from any OpenVINO toolkit 2020.1 embedded tools, please let us know.
