Thanks !

@LucaswasTaken Thanks for this solution. I was facing the same issue in Ubuntu 18.04. I followed your suggestion and now it is installed successfully.

Following this comment, installing libosmesa6-dev with sudo apt install libosmesa6-dev solved the problem for me with Ubuntu 18.04 and python 3.7.

Thanks for sharing your solution here !

@bjoernpl in my case it didn't work but @LucaswasTaken worked seamlessly

Yeah, I use Ubuntu 20.04 and Python 3.7 and you should to upgrade to 3.8.5 version then I had some problems with OpenCV sklearn, easydict modules, but is only to look a little bit in Stackoverflow and everything is gonna be okay 👍

For me this commands resolve this errors:

pip install -U scikit-learn scipy matplotlib

pip install -i https://pypi.tuna.tsinghua.edu.cn/simple --default-timeout=1000 EasyDict

This worked for me

sudo apt install libosmesa6-dev
sudo apt-get install build-essential
sudo apt-get install libgl1-mesa-dev
sudo apt-get install libglu1-mesa-dev
sudo apt-get install freeglut3-dev
