Does MNN supports intra_op_num_threads to configure number of physical cores? numThread is not helping in this.

Hi,
I am facing a strange issue, as soon as I integrate the mnn pymnn api with fastapi / flask server, it can only utilize a single physical cpu core at max. whereas in onnxruntime there is an option named intra_op_num_threads using which we can configure the number of physical core to be used. I tried numThread config while creating the session but it is not utilizing all the cores.

is there a way?

Thanks

@jxt1234 I created a PR to build pymnn with OpenMP, as using OpenMP build resolves the issue when pymnn is used with fastapi / flask server.
