mutex error on MacOs when using SetFit

[CassNot]

Hello,

I am trying to run a QML model using SetFit model from Hugging Face as the model body while the classification head, trained on top of it, is quantum (following this work).

However, on MacOs, if I create an environment (here with micromamba but the issue is the same with virtualenv and python venv):

#Create new environment (python version is 3.12.3)
micromamba create -n quantum_env python=3.12

# Activate it
micromamba activate quantum_env

# Install torchquantum 
cd /path/to/torchquantum
pip install --editable .

# Install setfit
pip install setfit

and I run a simple script

# Test imports separately
print("Importing torch...")
import torch

print("Importing torchquantum...")
import torchquantum

print("Importing setfit...")
from setfit import SetFitModel

the setfit import stalls and I get
[mutex.cc : 452] RAW: Lock blocking 0x107a47718 @

A few remarks:

• I am not getting this error in a GPU environment (H100) (Cuda version 12.8, python version 3.12.3)
• I am not getting this error with other QML libraries (merlinquantum, pennylane)

Thank you !
