Problems when running demo-FAILED: squeezenet1.1 Error

[李__朝辉]

Dear,

When I was running demo_squeezenet_download_convert_run.bat in C:\Program Files (x86)\IntelSWTools\openvino\deployment_tools\demo\, it always say that Failed: squeezenet1.1 Error. I have uninstalled OpenVINP and re-installed many times but it seems that it doesn't work. I was wondering if it is possible for you to help me solve this problem.QAQ

Besides, when it downloads models or squeezenet1.1, it always say 

The connection attempt failed because the connector did not reply correctly after a period of time or the connected host did not respond

There are all instructions that cmd offers:

Thank you so much!!

Hi,

The issue seems to be due to network proxy. Due to this, the model downloader could not download the model.

Set the proxy if any or try with a open network.

I am sorry but I have no idea why my post didn't get posted.

I am using ubuntu18_dev:2020.2 docker image and I found that /opt/intel/openvino/deployment_tools/inference_engine/lib/intel64/libcpu*.so is missing. I cross-checked ubuntu18_dev:2019_R3.1 and find the libcpu*.so (e.g. libcpu_extension_sse4.so). May I know how could I get my script running?

Thanks in advance
