When I try to import PYMC installed with pip, enpgk or the canopy GUI package manager, I tried all of them and without success.

I tried to install GFORTRAN with :
~$ sudo apt-get install gfortran-4.6
but I still get the same error.
(there are other questions very similar indeed, but usually the answer has to do with Anaconda and I'm using Canopy)
Any idea of what is going on ? I can import other packages.

On a fresh install of Raspbian 10 on Raspberry PI 3 B+, I am trying to install with Python 3.7 the numpy==1.19.5. The problem is that when I import pandas, I get this error:

If I keep the default installation of numpy==1.20.2, it works perfectly, but I have a requirement for any numpy version less than 1.20. I've tried some versions of pandas, but nothing works. I've hit a dead-end so I am asking here for help.
I am trying to import socket and I get the following error:

ImportError: cannot import name RAND_egd
I thought that perhaps my Anaconda installation was corrupted so I uninstalled and reinstalled Anaconda but the error persists.
I had tried what the other posts suggested except for editing socket.py due to Macos System Integrity Protection. My guess is that the problem lies elsewhere as I doubt that everyone has had to edit the file.
How can I find the source of the problem?
I have installed TensorFlow and wanted to check the installation. Here is the interaction with the python console.

Could anyone please tell what I am doing wrong? Thanks.
As Yaroslav noted, this is most likely from running too old a version of Python, or you don't have the funcsigs package installed. For the latter, try pip install funcsigs
I developed a Python package using Python 2.7 and 3.4, and now I'm trying to test it for 2.6 compatibility. So in Anaconda, I made a new conda environment for Python 2.6:
conda create -n python2.6 python=2.6.9 numpy scipy
But now, when I try to import some stuff from scipy:
$ python

Does anybody know a fix or a workaround? I'm using Mac OS X 10.9. The import works fine on 2.7 and 3.4.
I am evaluating the Enthought package. I installed the 32bit canopy (downloaded from https://www.enthought.com/downloads/) in Ubuntu.
$ sudo bash canopy-1.0.1-rh5-32.sh
Upon testing I don't see scipy in /usr/local/Canopy/appdata/canopy-1.0.0.1160.rh5-x86/lib/python2.7/site-packages:

Please help me: how can install the Python Canopy (including scipy, matplotlib etc.)? Do I have to manually install them? I thought the installer shell script installed all these automatically. Am I missing something?

Scipy is installed into a different virtual environment (~/Enthought/Canopy_64bit/System/). In general, you should be running the Python available at ~/Enthought/Canopy_64bit/User/bin/python as described here. Also look at this article for information on how to make Canopy your default Python
