I am using autokeras (version 0.3.6) to find the best model for my classification problem. The search process can take a lot of time and by providing enough time we can get better results. The problems is that it sometimes crashes. I am using ubuntu 16.04 LTS with python 3.6
I am using the following codes:
from autokeras import ImageClassifier
import autokeras
clf.fit(trdata_X, trdata_Y, time_limit= 1 * 60)
trdata_X, trdata_Y are the data that I provided as numpy arrays.
I get errors like
self.padding, self.dilation, self.groups)
RuntimeError: Given groups=1, weight of size [64, 192, 1, 1], expected input[128, 256, 32, 32] to have 192 channels, but got 256 channels instead
here are full logs:

I am trying to run the code multiple times to get results. I will appreciate of anyone helps me to find a solution for this problem.
