ValueError: Filter must not be larger than the input: Filter: (8, 8) Input: (3, 160)

Hi,

I’m having this issue when running train steering model:

(snakes) guy_pavlov84@instance-1:~/research$ sudo ./train_steering_model.py --port 5557 --val_port 5556
Using TensorFlow backend.

Any idea what that might be? This is the setup:

(snakes) guy_pavlov84@instance-1:~/research$ pip freeze
funcsigs==1.0.2
h5py==2.6.0
Keras==1.1.0
mock==2.0.0
numpy==1.11.2

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

in the view steering model.py file I found his error (ValueError: bad marshal data (unknown type code)) result when trying to execute the view steering model.py here is the result from the cmd prompt

Traceback (most recent call last): File "C:\Users\lenovo\Anaconda3\lib\site-packages\keras\utils\generic_utils.py ", line 229, in func_load raw_code = codecs.decode(code.encode(‘ascii’), ‘base64’) UnicodeEncodeError: ‘ascii’ codec can’t encode character ‘\xe0’ in position 46: ordinal not in range(128)

During handling of the above exception, another exception occurred:
