ImportError: cannot import name 'MultiHostDsn' from 'pydantic.networks' (/opt/conda/lib/python3.8/site-packages/pydantic/networks.cpython-38-x86_64-linux-gnu.so)

I followed the setup step by step, but got this Error when I am doing the last step(i.e. bash run_gradio.sh).Can you please help me to solve this problem? I really want to deploy Kosmos-2 locally. Many thanks ! File "/opt/conda/lib/python3.8/site-packages/fastapi/_compat.py", line 297, in from pydantic.networks import ( # type: ignore[no-redef]

Hi, you can try:

pip install --upgrade --user pydantic

[katsully]

@pengzhiliang tried that and it caused the following error: thinc 8.0.13 requires pydantic!=1.8,!=1.8.1,<1.9.0,>=1.7.4, but you have pydantic 2.0.2 which is incompatible. spacy 3.2.2 requires pydantic!=1.8,!=1.8.1,<1.9.0,>=1.7.4, but you have pydantic 2.0.2 which is incompatible.

Tried installing pydantic==1.7.4 but received the same error as the first post

Tried installing pydantic==1.8.2 but didn't work either.

[JierunChen]

After running pip install --upgrade --user pydantic I got the following error: thinc 8.0.13 requires pydantic!=1.8,!=1.8.1,<1.9.0,>=1.7.4, but you have pydantic 2.0.2 which is incompatible. spacy 3.2.2 requires pydantic!=1.8,!=1.8.1,<1.9.0,>=1.7.4, but you have pydantic 2.0.2 which is incompatible.

However, I am able to run the file gradio_app.py.

[pengzhiliang]

Yes, we are also trying to solve the problem of version conflict.

Found the magical combination of python library versions spacy==3.6.0 thinc==8.1.10 pydantic==1.10.10
