pip install trains fails

Question

upon running pip install trains in my virtual env

I am getting

I know that I am not supposed to run under sudo when using a venv, so I don't really understand the problem

running for example pip install pandas does work.

Python 3.8

How to install trains?

EDIT:

running pip install trains --user or pip install --user trains gives

ERROR: Can not perform a '--user' install. User site-packages are not visible in this virtualenv.

Looks like you've already borked your venv by running commands as root while having venv activated. Restore the ownership: run `id -un` to get the name, `id -gn` to get the group, then `sudo chown -R name:grp /home/epdadmin/noam/code/venv_linux/`, substituting `name` and `grp` with values you've obtained earlier. Then retry `pip install trains` — hoefling, Oct 11 '20 at 18:02
`pip install pandas` probably only works because you already have `pandas` installed, so `pip` doesn't do anything. Try e.g. `pip install pandas --force-reinstall`, most probably it will also fail. — hoefling, Oct 11 '20 at 18:04

You have two options:

Create a virtual environment and install your packages inside it (preferred)
Install your packages inside your user home directory by passing --user flag

pip install --user

Thanks. 1. I am already in a virtual environment, will edit now (although it is in the logs). 2. I have tried, and getting `ERROR: Can not perform a '--user' install. User site-packages are not visible in this virtualenv.` – Gulzar Oct 11 '20 at 15:55
@Gulzar can you uninstall `retrying` package and re-try? – Ankit Jaiswal Oct 11 '20 at 16:24
How? I will type the commands you tell me to. I am a long time Windows user, I just need to get my Python to work on a remote linux machine, so don't really know linux commands out of my head – Gulzar Oct 11 '20 at 16:25
@Martin.B same error when trying to `pip install retrying` after uninstalling. How do I solve this permission issue? it only happens on some installations, and not others. – Gulzar Oct 12 '20 at 10:04

The problem was a permissions problem for the venv. Another problem was trains required some packages that were not yet available with wheels on Python3.8, so I had to downgrade Python to 3.7

That venv was created using Pycharm, and for some reason it was created with low permissions.

There was probably a way to elevate its permissions, but instead I just deleted it and created another one using command line by

python -m virtualenv --python=/usr/bin/python3.7 venv

And now pip install trains worked.

Very annoying.

I had the same error with installing matplotlib in Ubuntu 18.

Running these lines worked for me:

sudo apt-get install python3-dev
apt-get install build-essential

As found on setup script exited with error: command 'x86_64-linux-gnu-gcc' failed with exit status 1
