Issue
import matplotlib.pyplot as plt
plt.plot([1,2,3])
plt.show()
input("Press enter to continue...")
If I run the script above within VS Code, or even within command prompt, the plot canvas only flashes for a fraction of a second and the program ends without any error. It doesn't even wait for perssing the Enter.
May be interesting:
- when I installed the Miniconda and set up the environment for the first time it worked. Then I installed
pydicomI successfully run the test script (with pydicom test image). When I tried to process my own DICOMs it requested for jpeg decoders etc. I installed them, and also others I don't remember. From some point it started to behave like described. - I tried to roll back to revision I knew it worked
conda install --revision XX, but that yielded an error - I removed the environment
conda remove --name myenv --alland created it from the scratch - I removed the environment and uninstalled the Miniconda, and redid everything
The problem still remains.
What can be the reason? How can I debug this? Is there any error log?

Solution
As of late, conda and matplotlib have been having issues.
You can try to downgrade freetype from 2.11.0 to 2.10.4 by doing conda install freetype=2.10.4
