I was getting the same error when running on python 3.7, however, the error disappears when running on python 3.6.

I try python test_op_mp.py --code_dir tmp_dir/ --smem_tiling --reg_tiling --op matmul_expr --shape 4096 4096 4096 base on https://github.com/microsoft/nnfusion/blob/osdi22_artifact/artifacts/get_started_tutorial/README_GET_STARTED.md, and get the same issue
