training error information about deepxi HOT 6 CLOSED

Is it necessary to run install step 2 and 3? I don't install them.

from deepxi.

Validation is not computed for epoch 0, as the network has not completed an epoch, so it is set to infinity until an epoch has been completed, see the initialised param 'val_error' on line 153:

epoch_par = {'epoch_size': len(args.train_s_list), 'epoch_comp': 0,
'start_idx': 0, 'end_idx': args.mbatch_size, 'val_error': float("inf")} # create epoch parameters.

As with your error, can you tell me what line of the script you are getting the error?

from deepxi.

Thank you!
After the first epoch is finished, then I get some error information as follows:

from deepxi.

can you please check your args.val_s, args.val_d, args.val_s_len, args.val_d_len, and args.val_snr numpy arrays? e.g. print(args.val_s.shape) to check if they are the right shape.

from deepxi.

@anicolson , Thank you for your help! I get it. Snr information don't be included in my val data's file name.
Another question:
Must I set snr level for each training data and val data on their file name?

from deepxi.

Only for the validation set. It's just so the validation set is always the same. Please read the following and can you tell me if you understand it:

For the validation set only:

Identical filenames for the clean speech and noise must be placed in 'val_clean_speech'
and 'val_noise', with the SNR at the end of the filename. The format of the filename is:
'x_y_zdB', where 'x' is the clean speech name, 'y' is the noise source name and z is the SNR level.
The clean speech and noise will be mixed together at the SNR level specified in the filename during
validation

As an example:
'./val_clean_speech/198_19-198-0003_Machinery17_15dB.wav' contains the clean speech,
and './val_noise/198_19-198-0003_Machinery17_15dB.wav' contains the noise. The number
of samples in the clean speech and noise must be identical.

This must be done, as the clean speech and noise used to create the noisy speech
(noisy speech = clean speech + noise) are required to compute the a priori SNR target.

Thank you
