File Exists Error

[Emily D]

I’m trying to train a duration model using run_lstm.py and it keeps crashing and giving the error message: “OSError: [Errno 17] File exists: ‘/Users/s1564218/Documents/dnn_combo2/nnets_model'”. I’ve tried both the one on /Volumes/Network/courses/ss/dnn/dnn_tts and a local one I’ve downloaded – the error occurs on both.

How can I fix this?

Thanks!

(the full error message is as follows:)

The fix is easy, and just needs a simple improvement to the code. One obvious fix would be to wrap a “try….except” around the os.makedirs function call. The exception that you need to catch (and then ignore, perhaps printing an informational message to the log) is OSError

[Emily D]

That’s what I was thinking, but I don’t see any calls to makedir that are not wrapped in either a conditional or a “try…except”. I’ll do some debugging and see if I can track down which one is causing the problem.

[Srikanth R]

If the number of frames in the input file and output file doesn’t match, the same error appears along with another error indicating a mismatch in the frame length. So, please check other errors as well if appeared any.

Please attend the upcoming session on Merlin where I’ll explain step-by-step procedure to implement/debug duration modelling.
