error in ImageClassifier.ipynb on Colab

[Python-Ninja-Hebi]

Hello,

I tried ImageClassifier.ipynb with gpu on colab.research.google.com

In cell

clf.fit(x_train, y_train, epochs=3) # each model is trained for three epochs

I got

---

UnknownError Traceback (most recent call last)
in ()
7 # 20% of the data is used as validation data by default for tuning
8 # the process may run for a bit long time, please try to use GPU
----> 9 clf.fit(x_train, y_train, epochs=3) # each model is trained for three epochs

UnknownError: Failed to get convolution algorithm. This is probably because cuDNN failed to initialize, so try looking to see if a warning log message was printed above.

What can I do?

Best regards
