Pythontex and TikZ externalization

[Nnomis]

Is it possible to externalize TikZ pictures ?
I read on stack that it seems like the answer is no.
I'm using pycode and pysub everywhere to write exercices.
Can I hope a solution ? It would be so amazing.
Currently the only things that really make my compilations slow down are the tikzpictures, and I'm kind of desperate about that...
I'm using subfiles waiting for a better solution...

PythonTeX is not currently compatible with TikZ externalization. It may be possible to add support for that at some point in the future, so I will leave this issue open for now.

Possible workaround: If you are generating the TikZ code using Python, you could save the TikZ code to its own separate file and then use Python's subprocess.run() to create a PDF from this.
