Facing issues while installing tensorflow or any other package behind the proxy :
First try :
Run the command :
pip install --upgrade tensorflow
Output :
Retrying (Retry(total=4, connect=None, read=None, redirect=None, status=None)) after connection broken by 'ProtocolError('Connection aborted.', ConnectionResetError(10054, 'An existing connection was
forcibly closed by the remote host', None, 10054, None))': /simple/tensorflow/
Second try :
Then I provided the proxy details along with the command
>pip install --upgrade tensorflow --proxy http://user:passwd@xxx.xx.x.xx:80
Output error :
Retrying (Retry(total=4, connect=None, read=None, redirect=None, status=None)) after connection broken by 'SSLError(SSLError(1, '[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:83
3)'),)': /simple/tensorflow/
Third try as suggested on pip install fails with "connection error: [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:598)":
pip install --upgrade tensorflow --trusted-host pypi.org --trusted-host files.pythonhosted.org --proxy http://user:passwd@xxx.xx.x.xx:80
Output :
Same as above.
Can anyone help ??

回答1:
I would suspect that you might need to set your proxy environment variables on your machine to use your proxy. Try setting the following (assumming your on a Linux or Mac OS):
export HTTP_PROXY=http://user:passwd@xxx.xx.x.xx:80
export HTTPS_PROXY=https://user:passwd@xxx.xx.x.xx:443
You don't necessarily need to set the HTTPS_PROXY variable but it can't hurt to do so
Then try running without the flags
pip install tensorflow

I had a similar issue after some update mix-ups between pip and apt. Following the suggestions on some SO page that I don't recall I've launched
sudo python -m easy_install --upgrade pyOpenSSL
and got the things running again.
LE: might've misread the problem.
