Can not Start Pylustrator

[PhysXu]

When I run import pylustrator, there always has an error of No module named 'matplotlib.backends.backend_qtagg'
Could you give some suggestions to solve this issue?

[rgerum]

which matplotlib version are you using? I guess it's a matplotlib version issue.

Thanks very much for the reply.
The version of matplotlib is 3.4.3, please see below:

I have tried it in Jupyter_lab and Jupyter_notebook, the same error.

BTW, as I am new to Python, What can I do if I need to install a certain version of matplotlib?

[rgerum]

you can use

pip install matplotlib==3.6.2

in the command line.

But I will have a look at see that I can fix it to work also with the older matplotlib version again.

I noted in the pylustrator website, it said that ** The package depends on:

numpy, matplotlib, pyqt5, qtpy, qtawesome, scikit-image, natsort**.
Could you tell me which version of those packages I need to install to support PyLustrator?
Thanks very much!

[rgerum]

natsort = ">=2.0.0"
numpy = ">=1.0.3"
matplotlib = ">=2.0.2"
PyQt5 = ">=5.6"
qtawesome = ">=0.5.0"
scikit-image = ">=0.7.0"

this is what minimal versions should be supported. But apparently there is a problem with the support of older matplotlib versions. if you use matplotlib==3.6.2 it should work.

Succeed after I updated my matplotlib!
Thanks very much for your help!

I have an additional question:
As I used the JupyterLab, after I close the window of pylustrator, the cell was still running/stuck.
Please see below:

How to solve/avoid this?

I tried around a bit and I think if you remove the %matplotlib qt pylustrator opens and the cell finishes after pylustrator has been closed.
