Kaldi_io error reading .scp/.ark files with python

Question

I need to read some scp file with the following code:

for key,vec in kaldi_io.read_vec_flt_scp('raw_mfcc_dev_clean.1.scp'):
    print("mfcc of id ",key,"is equal to ",vec)

here's a line in the scp file: 1272-128104-0000 raw_mfcc_dev_clean.1.ark:17

here's the error I get:

FileNotFoundError: [Errno 2] No such file or directory: 'raw_mfcc_dev_clean.1.ark:17\r\n'

P.S this directory raw_mfcc_dev_clean.1.ark exists
