When i try to upload my newest models i have the following error:

```auto
|11/21/2023 7:39:47 AM|File "/usr/local/lib/python3.10/pickle.py", line 331, in _getattribute|

```

What is wrong here? Anyone else having this issue?

I had the same error.  
I downgraded cloudpickle to 2.2.1 and solved this error.

i get the same error even after downgrading to 2.2.1. i tried 2.1.0, 2.2.1, 3.0.0 . any ideas?

cheers

EDIT: I solved it… 2.2.1 does indeed work, my downgrade had not worked properly… If you encounter a similar issue, you can check what package version is actually loaded by running

> import cloudpickle  
> print(cloudpickle.\_\_version\_\_)

Bumping this up as I’m getting the same error when trying to submit triggered when a sklearn model is part of predict.

Is there a known issue with sklearn’s model persistence using cloudpickle? I see that cloudpickle offers no forward compatibility guarantees - could that cause issues during submission?

hmm sweet, figured it out, downgrading to 2.1.0 works if I use TPU runtime. It was bringing dependency conflicts when running in CPU. Resolved 🤖
