Can anybody help me get txtai working on my M2 Mac?

I created a brand new conda environment, then pip install txtai[all]. Then I did brew install libomp and export OMP_NUM_THREADS=1 but no joy.

It crashes in the 01_Introducing_txtai.ipynb notebook at the line:

embeddings = Embeddings(path="sentence-transformers/nli-mpnet-base-v2")

There is no console output which might help narrow down the issue.

Does anybody have any more hints to get it working? This is/should be a clean environment and it doesn't work out the box.
