Unable to install plot.ly with wheel on python 3.7 behind constraining firewall

Question

I'm trying to install the plot.ly packages on my professional computer, i'm behind firewall, I have not the proxy information to set up a connection for pip .

So I download a .whl files and try to install it. (get it from https://pypi.org/project/plotly/ ) Whatever the configuration i've tried ( anaconda 3.7, pycharm 2.7, pycharm 3.7 ) i get the same message:

Processing c:\users\xxxx\downloads\plotly-4.3.0-py2.py3-none-any.whl
Collecting retrying>=1.3.3 (from plotly==4.3.0)
Could not find a version that satisfies the requirement 
    retrying>=1.3.3 (from plotly==4.3.0) (from versions: )
No matching distribution found for retrying>=1.3.3 (from plotly==4.3.0)

Answer 1

pip is trying to download the dependency retrying , which it can't because of your firewall. Simply download retrying from pypi , install it by typing

pip install <path to the downloaded file>

then try installing plotly again. Note that you will have to do this for every requirement of plotly .
