error when launching gradio app

[vlxxc]

when launching gradeio app i get the following error: ImportError: cannot import name 'Schema' from 'pydantic'

[grebz-dev]

I am also experiencing this issue. Installed via docker and running python 3.10

Got this issue runing via collab, and docker. Updating gradio, fast api, and lighting seemed to fix it, but now it seems to quit without throwing an error, or giving confirmation that gradio was launched.

[Ainaemaet]

Same issue and no answer from the devs. Looks like it's happening to a lot of other people to (in other places), not sure how to fix it...

Yup, here with the same problem -

Same here. Wsl Ubuntu docker giving same errors.

[mashb1t]

same for me

Hi everyone! Sorry for the inconvenience. I already fixed this problem in the latest commit. Please pull the new code and try again. You may also need to reinstall gradio:

pip uninstall gradio gradio_client pydantic pydantic_core 
pip install gradio==4.11.0

Note that if your network cannot connect to huggingface, remember to add HF_HUB_OFFLINE=1 DIFFUSERS_OFFLINE=1 TRANSFORMERS_OFFLINE=1 before the gradio launch command.

The gradio demo is a very basic interface for some text-to-3D pipelines, and does not support image-to-3D yet. Welcome the contribute and make it better!

Still facing the pydantic problem with a new error:

Also having this issue "ImportError: cannot import name 'Schema' from 'pydantic' " .... Using gradio==4.11.0

[FishWoWater]

the problem seems to stem from old and mismatch version of fastapi (against gradio==4.11.0 and pydantic==2.5.2)

pip install -U fastapi pydantic works well for me

[Ethan-Otto]

On the docker container, I pip install fastapi and pydantic yet when I run gradio I get the following

To create a public link, set share=True in launch(). Exception in thread Thread-4 (_do_normal_analytics_request): Traceback (most recent call last): File "/home/dreamer/.local/lib/python3.10/site-packages/httpcore/_exceptions.py", line 10, in map_exceptions yield File "/home/dreamer/.local/lib/python3.10/site-packages/httpcore/_backends/sync.py", line 168, in start_tls raise exc File "/home/dreamer/.local/lib/python3.10/site-packages/httpcore/_backends/sync.py", line 163, in start_tls sock = ssl_context.wrap_socket( File "/usr/lib/python3.10/ssl.py", line 513, in wrap_socket return self.sslsocket_class._create( File "/usr/lib/python3.10/ssl.py", line 1100, in _create self.do_handshake() File "/usr/lib/python3.10/ssl.py", line 1371, in do_handshake self._sslobj.do_handshake() TimeoutError: _ssl.c:990: The handshake operation timed out

the problem seems to stem from old and mismatch version of fastapi (against gradio==4.11.0 and pydantic==2.5.2)

pip install -U fastapi pydantic works well for me

Unfortunately this didn't work for me.

ImportError: /home/dreamer/.local/lib/python3.10/site-packages/tinycudann_bindings/_89_C.cpython-310-x86_64-linux-gnu.so: undefined symbol: _ZN2at4_ops5zeros4callEN3c108ArrayRefINS2_6SymIntEEENS2_8optionalINS2_10ScalarTypeEEENS6_INS2_6LayoutEEENS6_INS2_6DeviceEEENS6_IbEE

I think the problem is this:

pip install -U fastapi pydantic installs fastapi-0.112.0 and pydantic-2.8.2 pydantic==2.8.2 does not provide 'Schema', pydantic==1.10 provides it. but gradio==4.11.0 requires pydantic>=2.0 also, lightning==2.0.0 requires fastapi<0.89.0
