Hello! Duda from Weaviate here.
There seems to be an update that was not yet released to pypi that is preventing on using simsimd on python3.13, as per this issue: https://github.com/langchain-ai/langchain-weaviate/issues/212
Meanwhile, if for development, you can install it directly from source with
pip install -e "git+https://github.com/langchain-ai/langchain-weaviate.git/#egg=langchain-weaviate&subdirectory=libs/weaviate"
or you can run Python3.12
Hope we can have that released soon.
Thanks!
