Hey
I solved the problem following your instructions, thank you very much.

from research.

Have you solved this problem?
I have got the same problem as you.

from research.

Yes, at some point in a new release of keras the order of parameters of input_shape and output_shape was changed. To solve this we need to make two adjustments:

1. input_shape=(ch, row, col) == > input_shape=(row, col, ch) (line 28 in train_steering_model.py)
   the same for output_shape
2. flip the input data accordingly - add two lines after line 17 and before line 18 in train_steering_model.py:
   X = numpy.swapaxes(X, 2, 3)
   X = numpy.swapaxes(X, 3, 4)

from research.

Hey, I solved the problem following your instructions, then another problem is appear:
After I trained the steering model, then use the following command to visualize the results:
"./view_steering_model.py ./outputs/steering_model/steering_angle.json"

It got errors:
Exception: Error when checking : expected lambda_input_1 to have shape (None, 160, 320, 3) but got array with shape (1, 3, 160, 320)

We need to modify the code in "view_steering_model.py" to slove the problem?

from research.

Yes, we have to change the code near the line 113 and 114 according to above instructions.
Good luck.

from research.

Yes, thank you! I have changed the code near line 115,

Before:
predicted_steers = model.predict(img[None, :, :, :].transpose(0, 3, 1, 2))[0][0]

After:
predicted_steers = model.predict(img[None, :, :, :].transpose(0, 1, 2, 3))[0][0]

Than, it works. Thank you.

from research.

hey can you tell me what the line from utils import load, save is doing and more importantly how i can install utils

@gpavlov2016 Your solution works for me too but ran into another issue.

Using TensorFlow backend.

Any ideas why I might be seeing this?

from research.

I was able to figure out that I didn't include numpy in my imports in the train_steering_model.py file and hence it was giving me the above error....
However now I am running into the same issue as #27 and my training gets killed even before the 2nd epoch is done. Any ideas or suggestions will be very helpful.
FYI - I don't think I have a powerful machine on which I am running this on as this seems to be aresource issue. What are the minimum system requirements for me to have it train successfully?

same problem occurred
