File Missing

When run python benchmark_mat.py I got

Traceback (most recent call last):
File "/{python_path}/lib/python3.8/site-packages/scipy/io/matlab/mio.py", line 39, in _open_file
return open(file_like, mode), True
FileNotFoundError: [Errno 2] No such file or directory: '/{code_dir}/data/cover.mat'

During handling of the above exception, another exception occurred:
