我遇到了一个项目问题，我试图使用loadmat函数但出现上述错误：
File "project.py", line 107, in load_data
return loadmat(filename, appendmat=False)['data'].squeeze()
File "/home/xx/.virtualenvs/cv/local/lib/python3.5/site-packages/scipy/io/matlab/mio.py", line 136, in loadmat
matfile_dict = MR.get_variables(variable_names)

OSError: could not read bytes
我有导入：
from scipy.io import loadmat
