I done a project 4-5 years before, currently i needed that project now, there i used specific python packages, for example, matplotlib==1.5.1 and scipy==0.19.0 is needed and more.
To run that project now, I created a virtual env. with python version 3.5, but when installing those packages, I got Error:could not find a version that satisfies a requirement
for all the python packages
I tried many solutions, but all ended in the same error
How to install those specific version, now? and, what are the possible ways to install those packages?
thanks
