warning: Unable to connect optimized C data functions [No module named '_testbuffer'], falling back to pure Python

[aaronmarkham]

Describe the bug and how to reproduce it I get this warning both during embeddings creation and running the model.

Unable to connect optimized C data functions [No module named '_testbuffer'], falling back to pure Python

Expected behavior Maybe things would run faster if it could find what it is looking for.

Environment (please complete the following information):

• OS / hardware: Windows 10 Home
• Python version: 3.11

Already had MinGW installed and gcc is selected (mingw32-gcc-bin). Assuming this is what the readme is referring to.

Had similar issue, found that downgrading the clickhouse-connect package version solved it for me. pip install --upgrade clickhouse-connect==0.5.22

Excellent. Thank you. pip install --upgrade clickhouse-connect==0.5.22 worked for me too.

Seems like clickhouse-connect got fixed. Using the latest version fixed it for me.

Had to add "--user" because of restrictions but it worked for me. Thanks!
