multilingual-e5-small-optimized

like 11

Hi,
When I use the conversion tool model_zoo_importer.py from Deep Java Library on this model I get the error:

Failed to load model: elastic/multilingual-e5-small-optimized. Unable to load weights from pytorch checkpoint file for '/path/to/pytorch_model.bin' at 'path/to/pytorch_model.bin'. If you tried to load a PyTorch model from a TF 2.0 checkpoint, please set from_tf=True.

And also other exceptions.

I can convert other HF sentence similarity models without issues (also intfloat/multilingual-e5-small). If I Google on this error some responses mention that files may be corrupt, but when I compare the locally cached files with the ones I download from "Files and versions" I see no binary differences. I tried both under Ubuntu 20.04 (WSL2) and Windows 11 (errors differ somewhat). Does anyone has any idea how to resolve this issue?

This is the complete output of the conversion:
