Issue at step 8 test.py about fakebob

[GolferChen]

Since the file is not empty, I infer maybe it is the file permission problem. Please let me know whether or not, so I can update the code to resolve the permission problem automatically.

[GolferChen]

For quick debug, please add the following code to Line 253 in ivector_PLDA_kaldiHelper.py and re-run the code.

permission_command = "chmod -R 777 " + self.ivector_dir
import os
os.system(permission_command)

The programe will run well after adding the above code if the issue is indeed raised by file permission problem.

Hmm, I didn't notice this before but it seems that the problem is ivector.scp is put under "/Users/user1/FAKEBOB/test-iv-CSI/"
instead of "/Users/user1/FAKEBOB/test-iv-CSI/ivector/"

[GolferChen]

Actually, there should be two ivector.scp files, the one placed in /Users/user1/FAKEBOB/test-iv-CSI/ is for training voices (i.e., the enrollment voices) , and the other one placed in /Users/user1/FAKEBOB/test-iv-CSI/ivector/ is for testing voices (i.e., voices to be scored).

So please check whether both files exist.

[GolferChen]

Are you sure every step of kaldi runs successfully, including mfcc extraction, vad decision and ivector extractor ?

The warning message "empty argument to --cmd option" appears many times in your provided log.

I doubt that the ivectors for testing voices did not get generated, so /Users/user1/FAKEBOB/test-iv-CSI/ivector/ivector.scp does not exist. You can verify this by checking if there are many .ark files in /Users/user1/FAKEBOB/test-iv-CSI/ivector/.

[hypernovas]

Ok. The only file in /Users/user1/FAKEBOB/test-iv-CSI/ivector/ is trials

[GolferChen]

I got it. The ivectors for testing voices did not get generated. Can you check /Users/user1/FAKEBOB/test-iv-CSI/mfcc/ ? Are there many ".ark" files there ?

[GolferChen]

I doubt that your step 7 actually did not run normally.

Got a chance to set up an ubuntu environment, it just works more smooth. Everything is working fine now. Some notes that might help.

1. data.tgz file contains some links (instead of audio files) which create some errors
2. Some weird bugs can be fixed by setting up nj to be 1, there could be some sync problem in local machine

Thanks a lot for all helps.

[GolferChen]

Ok. Thanks for your feedback.
