Indexing elements must be in increasing order

[minghigh]

when I run the following code (demo.mp3 is my example music)

python acapellabot.py demo.mp3

got errors :

Traceback (most recent call last):

    int(a)

During handling of the above exception, another exception occurred:

Hi there,
I am facing a similar problem when loading weights file:
TypeError: Indexing elements must be in increasing order

This error seems to have the same cause as above.
I am using same libraries set of @minghigh, but running on mac.

Thanks for pointing this out!

The weights were saved from Theano 0.9.0 using the 'tf' dim ordering–it looks like they don't work with the TensorFlow backend (tested on CentOS 7.3 with both TF/Theano installed and the packages you listed; tf backend gives the same unorderable types error, but Theano works).

I'll see if I can figure out a way to make the weights interoperable (assuming that this is some sort of configuration mistake on my end). In the meantime, switching to Theano should hopefully resolve the issue (don't forget to change ~/.keras/keras.json):

{
    "backend": "theano",
    "image_dim_ordering": "tf"
}

I change the backend to theano but have the new problem:

@arlose Regarding the "channel dimension of the inputs should be defined. Found None." issue–You're probably using the th dimension ordering; the trained weights were saved in tf ordering. Could you try opening ~/keras/keras.json and specifying tf ordering:

{
    "backend": "theano",
    "image_dim_ordering": "tf"
}

I think there's a way to set the ordering in the script itself, so I'll see if I can do that to save people some trouble in the future.

[madebyollin]

@arlose Also, are you running python 3? From the printout it looks like you're using python 2, but it won't work in python 2 without some adjustments (the issue you're getting there is because of the change in behavior of the division operator, you could probably fix it with some calls to round())

[arlose]

@madebyollin thanks
i just resolved it

[mktanguturi]

Hi @madebyollin ,
Is this issue resolved with Tensorflow backend? Or still we need to use Theano backend?

Kindly confirm.

Thanks
