@ptrblck Hi sir, I have changed this dst to the required different folder as 'E:\\Python_On_All_Dataset\\IEMO\\long_codes\\multiscale_att_impro_only\\head_fusion-master\\IEMOCAP'. But its throwing the error:
[WinError 183] Cannot create a file when that file already exists: 'E:/dataset/data/IEMOCAP_full_release\\Session1\\sentences\\wav\\Ses01F_impro01\\Ses01F_impro01_F000.wav' -> 'E:\\Python_On_All_Dataset\\IEMO\\long_codes\\multiscale_att_impro_only\\head_fusion-master\\IEMOCAP'
Sir let me explain it again: Here I want to change the data files name which are stored in original directory of my dataset, and renamed files need to be stored at other location so that my original data files are not disturbed. But why is it saying these files already exist there. The destination folder IEMOCAP is empty 
Regards
