Can't Load the Weights

[zhipeng-fan]

Hi! I am new to this project and Keras. I have downloaded the weights file from the dropbox into /model/keras/model.h5. However, I kept getting this error:

$ python demo_image.py --image sample_images/ski.jpg
Using TensorFlow backend.

Traceback (most recent call last):

OSError: Unable to open file (Unable to lock file, errno = 5, error message = 'input/output error')

Any ideas on how to fix this?

@zhipeng-fan It seems that there is a problem with opening the file. "....Unable to lock file" Check file access permissions on your machine.

@michalfaber Yeah. It could run on my own laptop but not the cluster. I guess it is the permission problems. Thanks any way! Great job to transfer the original work into Keras!

Hi Michal,

I also came across some problem with load_weights() using the downloaded file from the dropbox /model/keras/model.h5
The error I got is as follows:

ValueError: Dimension 0 in both shapes must be equal, but are 1 and 38 for 'Assign_140' (op: 'Assign') with input shapes: [1,1,128,19], [38,128,1,1].

And my kerns.json is set to

{
"epsilon": 1e-07,
"floatx": "float32",
"image_data_format": "channels_last",
"backend": "tensorflow"
}

Any suggestions? Thank you so much!
