In my case (Dockerfile or Linux), we wanted to get pip modules installed from requirement*.txt files, which had locked-in module's versions defined in the file and fetched from an internal Artifactory server (rather than going to online i.e. pypi.org)
Ex: requirements.txt file(s)
<pre><code>numpy==1.16.2
pandas==1.0.3
..
...
</code></pre>
To fix the issue: I had to use <code>NO_PROXY=&lt;value&gt;</code> available as an environment variable.
Let's say, if you artifactory server is: my-artifactory.company.local or my-artifactory.company.com, then all we need to ensure is that <code>NO_PROXY</code> variable has that hostname's &quot;domain&quot; part listed in its value.
i.e. for
my-artifactory.company.com or my-artifactory.company.local, value inside
NO_PROXY variable must have: <code>,.company.com,.company.local,...</code> in it.
Sample exported variable (at command line $ prompt):
<code>export NO_PROXY=localhost,127.0.0.1,169.254.169.254,169.254.169.123,.somecompany.com,.company.com,.company.local,pki.company.com,s3-us-gov-west-1.amazonaws.com,s3-fips-us-gov-west-1.amazonaws.com,rds.amazonaws.com,10.201.12.244,10.201.44.62,10.201.32.261</code>
====
If you are using a <code>Dockerfile</code>, then, ensure you have ARG/ENV variable are set correctly.
ARG is used during build time (can be overridden at command line using --build-arg option sent to <code>docker build -t tag .</code> where it'll search current directory for a Dockerfile and create an image. ENV is used at run time (<code>docker run</code>) and can be overridden as well.
Sample Dockerfile is:
<pre><code>FROM python:3.7

MAINTAINER giga.sangal@company.com

ARG HTTP_PROXY=http://proxy.ext.company.com:80

# If there are 3 requirements files in source control, I'm copy all for pip install, you don't have to. Use what modules you want / file you want.

</code></pre>
The main line, which solved the issue in my case, was using the NO_PROXY (as listed above).
Any issues related to pip module not found, or module version not found, or any SSL errors <code>SSLError(SSLCertVerificationError</code> like errors, went away after applying the above NO_PROXY at cmd line or in Dockerfile:
<pre><code>WARNING: Retrying (Retry(total=4, connect=None, read=None, redirect=None, status=None)) after connection broken by 'SSLError(SSLCertVerificationError(1, '[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: self signed certificate in certificate chain (_ssl.c:1091)'))': /simple/requests/
</code></pre>
or
<pre><code>ERROR: Could not find a version that satisfies the requirement requests
ERROR: No matching distribution found for requests
</code></pre>
or
<pre><code>ERROR: Could not find a version that satisfies the requirement numpy==1.16.2
ERROR: No matching distribution found for numpy==1.16.2
</code></pre>

I downloaded Python 3.6.1 and it came with Pip preinstalled. I wrote this command to install numpy 

<pre><code>C:\Python36-32&gt;python -m pip install numpy 
</code></pre>

To which I got this as the output: 

<blockquote>
 Collecting numpy Could not fetch URL
 <a href="https://pypi.python.org/simple/numpy/" rel="nofollow noreferrer">https://pypi.python.org/simple/numpy/</a>: There was a problem confirming
 the ssl certificate: [SSL: CERTIFICATE_VERIFY_FAILED] certificate
 verify failed (_ssl.c:749) - skipping Could not find a version that
 satisfies the requirement numpy (from versions: ) No matching
 distribution found for numpy 
</blockquote>

How do I solve this? 
PS: I did this on Windows 10, Command Prompt running as administrator.
