Importing is very slow

[carlosperate]

In my dev environment (Macbook Pro 2020 i7) importing atproto takes over 3 seconds with Python 3.10, 3.11 and 3.12.

I couldn't find mentions of this in the issue tracker, so I assume this is not as expected?

$ python --version
Python 3.12.1

$ time python -c "from atproto import Client"

   sys time    0.22 secs    1.52 millis    0.21 secs

The Python 3.12 venv pip list output:

This is know one :( and comes from pydantic #441

Try “from atproto import models”. Should be the same bad result. Client itself is not a problem

Ah, sorry, I didn't realised there was a Discussions section in the repo as well.
Could the model imports be lazy loaded? Or is this something we need to live with until Pydantic had a chance to improve performance?

I have also noticed this. On my very fast dev system it takes 1.3 seconds, and on my raspberry pi 5, it takes about 4 seconds.

That's crazy slow.
