Pip fails to install tensorflow

Question

I'm trying to install tensorflow, on an offline computer with Windows 7. I have previously done this using pip on the whl file and it worked, but now that I'm trying to do the same with tensorflow-gpu, I get an unexpected error:

> pip install -v tensorflow_gpu-1.2.0-cp36-CP36m-win-amd64.whl

it seems that pip tries to download https://pypi.python.org/pypi/pip/json , which it was not trying to do before. How can I solve this?

Answer 1

For similar problems this helped me:

1. Set https_proxy env. variable to your HTTPS proxy:

    > set https_proxy=myproxy.org:port > pip install ... 

I suggest to set https_proxy as system or user-level env. variable for the future...

2. Or provide the proxy as a parameter to pip :

    > pip --proxy=myproxy.org:port ... 

AFAIK, on Windows 7, you can display your proxy settings by:

> netsh winhttp show proxy

(hopefully including httpS proxy, too...)
