"error 3 validation errors for Prediction" when running "replicate.run()"

[waelmansourx]

Everytime I use this command, with any model

replicate.run(
        "stability-ai/stable-diffusion:<api-code>",
        input={"prompt": "a 19th century portrait of a wombat gentleman"}
    )

I recieve this error:

Field required [type=missing, input_value={'id': ''}}, input_type=dict]

It should be the problem of updating the pydantic package to 2.0.Just reinstall version 1.9 will fix it. such as:

pip install pydantic==1.9

@SCUTlihaoyu This worked well. Thank you!

Hi @waelmansourx. Thanks for reporting this. Apologies for the inconvenience. As @SCUTlihaoyu mentioned, these are due to breaking changes in Pydantic 2.0 which was released a few days ago.

I'm looking into what it'd take to support both 1.x and 2.0. But in the meantime, pinning to 1.9 as @SCUTlihaoyu suggested should do the trick.

@waelmansourx @Mig29github @SCUTlihaoyu I just released version 0.8.4, which pins Pydantic to 1.x. This should solve the immediate problem you encountered with Pydantic 2 incompatibility.

As mentioned in #113, my goal is to update this library to support both Pydantic 1.x and 2.x in a future release.

Please let me know if you have any other issues with this. Thanks!

From https://pypi.org/project/pydantic/2.0/

Pydantic V2 also ships with the latest version of Pydantic V1 built in so that you can incrementally upgrade your code base and projects: from pydantic import v1 as pydantic_v1.

@simonw Thanks for pointing that out, and for #121. Curious that this V1 shim doesn't seem to be mentioned anywhere on https://docs.pydantic.dev/latest/.
