Error: issubclass() arg 1 must be a class

[bertello72]

with replicate version 0.23.0

Running this code:

import replicate
output = replicate.run(
"mistralai/mistral-7b-instruct-v0.1:5fe0a3d7ac2852264a25279d1dfb798acbc4d49711d126646594e212cb821749",
input={
"debug": False,
"top_k": 50,
"top_p": 0.9,
"prompt": "Can you write me a poem about steamed hams?",
"temperature": 0.7,
"max_new_tokens": 500,
"min_new_tokens": -1,
"prompt_template": "{prompt}",
"repetition_penalty": 1.15
}
)
print(output)

I got this error:

Hi @bertello72. Based on this issue, this looks like an incompatibility between typing_extensions == 4.6.0 and pydantic < 1.10.8. Try upgrading to pydantic 1.10.8 or higher and let me know if that fixes your problem.

It works updating pydantic to 1.10.8 Thank you
