Install_prerequisites_caffe.bat failing

[SteakStyles]

I have been attempting to run the demos under /deployment_toos/. However, whenever I run a demo, I get the message 

\Intel\openvino_2021\deployment_tools\model_optimizer\install_prerequisites\..\mo\utils\extract_release_version.py') was unexpected at this time. 

I've tried reinstalling the toolkit and starting the setup for the NCS2 but to no avail.

I'm running Windows 10 Pro on the latest update

Hi Sean Mulhall,

Thank you for reaching out. I also get this message when running the install_prerequisites_caffe.bat file.

For your information, it is required to use double quotation marks when specifying paths with spaces for windows.

However, in the original script of install_prerequisites.bat file, there are missing double quotation marks in the python_command and the errorlevel parts.

Hence, we need to add the double quotation marks in line 73, 83, 122 and 140.

For Example:

The default install directory of OpenVINO™ Toolkit is:

C:\Program Files (x86)\Intel\openvino_2021.3.394

Line 73:

Original line:

set python_command='python %~dp0..\mo\utils\extract_release_version.py'

Edited line:

set python_command='python "%~dp0..\mo\utils\extract_release_version.py"'

Regards,

Thank you, that solved my problem. However, I now have a different error:

I have Python 3.8 (Anaconda) installed for all users. 

echo %pythonpath% gives the following:

C:\Program Files (x86)\Intel\openvino_2021\deployment_tools\tools\post_training_optimization_toolkit;C:\Program Files (x86)\Intel\openvino_2021\deployment_tools\open_model_zoo\tools\accuracy_checker;C:\Program Files (x86)\Intel\openvino_2021\python\python3.8;C:\Program Files (x86)\Intel\openvino_2021\python\python3;C:\Program Files (x86)\Intel\openvino_2021\deployment_tools\model_optimizer;

I have the same error message:

Googled for some time, could not find any solution. This thread is the most close one, can you help?

Thank you

Hi Sean Mulhall,

I'm glad that you can solve your issue.

Next, based on the error:

ERROR: Could not find a version that satisfies the requirement openvino

ERROR: No matching distribution found for openvino

This happens because you are using Python 3.9 version. For your information, you have to use Python 3.6-3.8 64-bit version as a primary Python version because this is the python version supported by OpenVINO 2021.3 for Windows.

Refer to the link given below as your references:
