Error during running the Image Classification demo script after installing

[Hai_H_Intel]

I met the below error during running the Image Classification demo script after installing with below:

sudo ./demo_squeezenet_download_convert_run.sh

Anyone met same issue and does anyone know how to fix the problem? Thanks a lot!

Hi Huang, 

the prerequisites installation such as numpy library should have happened before this error, can you show the debug output in between "Configure Model Optimizer" and this error?

Doing pip3 install numpy should solve your issue, but we need to investigate why the pre-requisites call did not work properly in your case. 

Best,

Hi Severine, Thanks for looking into my issue. The information you requested as below: 

###################################################

Configure Model Optimizer

INTEL_CVSDK_DIR environment variable is not set. Trying to run ./setvars.sh to set it.
[setupvars.sh] OpenVINO environment initialized
Found existing environment. Skipping installing dependencies for Model Optimizer.
If you want to install again, remove venv directory. Then run the script again

###################################################

And I can't find the file 'setvars.sh', also in our install instruction, don't mention need to run it. Thanks!

I am try to install the numpy as you mentioned, but it is already install, so this issue may caused by another reason. Thanks!

Hi Huang, 

you can find the documentation on how to setup the environment variables here: https://software.intel.com/en-us/articles/OpenVINO-Install-Linux (search Set the Environment Variables). However, this is not the issue here.

I see you use CentOS, I was trying to reproduce your error with Ubuntu. I need to investigate what is causing the issue, it is maybe the virtual environment activation. This could explain the mismatch of  numpy installation.

Best,

Severine

 Hi Huang, 

it seems to be the virtual environment activation. If you comment the line 154, source $prereqs_mo_path/../venv/bin/activate , is it working?

Best, 

Severine

Thanks Severine!

As your suggestion, after I removed the venv folder and upgrade the cmake from 2.8 to 3.12, the issue fixed. Thanks!
