Understood. No problem.
Where is the Flask package installed?
On my Ubuntu 16.04 system, anaconda python and all python modules are
installed in my home directory. There is no virtual environment. When I
log-in the PATH environment variable is set so any invocation of python
uses the desired python distribution. All my python code is able to find
all other installed modules. There is history and legacy here.
My immediate objective is to have the Apache server boot and use the python
distribution in my home directory for all Flask/WSGI related processing.

LoadModule wsgi_module /usr/lib/apache2/modules/mod_wsgi.so
notes:
1) was able to successfully pip install mod_wsgi
pip install mod_wsgi
Requirement already satisfied: mod_wsgi in
./anaconda3/lib/python3.6/site-packages (4.6.4)
2) updated softlink to use new object

-rw-r--r-- 1 root root 207952 Jan 25 2016 mod_wsgi.so-3.5
3) server log shows the new mod_wsgi is being loaded.
