'str' object has no attribute 'decode'

[hasantha-nirmal]

Dear Sir,

I'm having this issue when I tried to run the pretrained weights or my owned trained weights.

'AttributeError: 'str' object has no attribute 'decode'

Is the error I finally getting. Your advice would be much appreciated.
Thanks

Loading pre-trained weights in svhn/weights.h5

I dropped the decode('utf-8') part but that gave me another bug.
You can see the link that has solution: https://stackoverflow.com/questions/28583565/str-object-has-no-attribute-decode-python-3-error

Now I am getting ValueError: Cannot feed value of shape (30, 2048, 1, 1) for Tensor 'Placeholder_318:0', which has shape '(1, 1, 2048, 75)'
Thanks

Thanks for the help. Yes I have tried that too. But it gives that error code as you mentioned . But I think this will help for some extent.

This repository describes a similar approach for localizing objects from regular cnn. ( I couldn't achieve this btw, hope you could figure this easily)

I've solved it, thanks to
