[Python] RuntimeError when reading wav file

I am following the https://github.com/mravanelli/SincNet library . I have followed the documentation as suggested. but I got the RuntimeError

I have changed the file access using sudo chmod +x /home/sathiyakugan/Downloads/TIMIT/data/lisa/data/timit/raw/TIMIT but it didn't solve the problem.

This is the syntax that I executed python3 TIMIT_preparation.py /home/sathiyakugan/Downloads/TIMIT/data/lisa/data/timit/raw/TIMIT /home/sathiyakugan/Documents/FYP/out data_lists/TIMIT_all.scp

and this is the error I received.

File "TIMIT_preparation.py", line 56, in <module>
[signal, fs] = sf.read(wav_file)
File "/home/sathiyakugan/.local/lib/python3.6/site-packages/soundfile.py", line 257, in read
