Installing tensorflow 1.14.0 on python2.7 on Ubuntu 20.04 - python-2.7

Question

I'm trying to install tensorflow 1.14.0 on my Ubuntu (20.04 LTS) machine.
I need the python version 2.7.
The cmd line I'm trying to execute is
$ sudo python2.7 -m pip install tensorflow==1.14.0
but it seems there is an issue with "grpcio". The output is the following one:

I have already tried to upgrade pip (20.3.4) and setuptools (44.1.1).
I also tried to install grpcio from a repository by following this guide https://pypi.org/project/grpcio/, but I get the same error.
Do you have any suggestion?
Thank you!

Answer 1

I had the same exat issue as you, upgrading pip wouldn't work in my case either.
I was able to install tensorboard on my platform by installing an older version of grpcio (in my case pip install grpcio==1.20.1).
You will see some warnings on execution about some missing dynamic libraries which are ok for me, but you might want to try other grpcio version.
