Hi,

Great work on this project. I am trying to create a desktop app which loads a model created by the FLAML library (saved as a pickle file) and make prediction by this model. When I try to load the model (pickle.load(open('model.pkl', 'rb'))) I get the following error:

ImportError: Could not load dynamic lib: /lib/python3.10/site-packages/scipy/linalg/_fblas.cpython-310-wasm32-emscripten.so Error: bad export type for ztrsm_: undefined

Traceback:

Do you know how to solve it and load the model?

Thank you for your answers.
