I was running app.py on my machine, any solution?

[repulsio]

I saw this error too. I believe the root cause is a missing package. If you share the full logs, the error should come before what you pasted

I have a full working guide here too: #222

[usamashami11]

Yes, I am facing the same error.
When I ran the code on my local Ubuntu Machine having Nvidia RTX3090, Gradio Apps worked fine for both text and image model. However, when I am trying to run them on my GCP VM Instance, running Ubuntu with Nvidia A100, the URLs for localhost and public app are generated, but it's showing Internal Server Error in the UI, and in the code outputs/logs, it says the same error, which loops a bit too. Ultimately, I have to close the app, so I don't know what's the issue here!

Just to mention that I installed all the packages the same way and both used CUDA 11.8 and everything else is same, so I doubt, it there is anything missing.

@usamashami11 Maybe pydantic needs to be downgraded?

gradio-app/gradio#10662 (comment)

[kadenkat]

I ran into this issue as well. Downgrading my pydantic to 2.10.6 did the trick as noted by comments in gradio-app/gradio#10649.

[usamashami11]

Just to give update, I didn't try by downgrading the package but modified the utils.py file of gradio_client in two instances

1. The top of get_type(schema):

def get_type(schema):
    if isinstance(schema, bool):
        schema = {}
    …

2. The top of _json_schema_to_python_type(schema, defs) (around line 937 in mylocal copy)

def _json_schema_to_python_type(schema, defs):
    # Coerce bare booleans into empty‐schema dicts
    if isinstance(schema, bool):
        schema = {}
    …

and it fixed my error.
