Hitting error when trying to generate .pb model suggested in OpenVino documentation

[Mariam_R_Intel]

Hello,

Here is the error that I hit when trying to use any of the TF slim model to get the frozen .pb model. This timeout error is seen for any model in Slim that is suggested in OpenVino documentation. Any clue why this timeout been hit?

Hi Mariam, 

this is an issue with your proxy. You should use on Windows before calling the script:

set https_proxy=yourproxyhere:port

set http_proxy=yourproxyhere:port

Best,
