Tensorflow 联合学习在 colab 中出现错误

Question

I am trying to run the Tensorflow federated tutorial on colab ( https://colab.research.google.com/github/tensorflow/federated/blob/v0.5.0/docs/tutorials/federated_learning_for_image_classification.ipynb#scrollTo=coAumH42q9nz )

However, so far, the from tensorflow_federated import python as tff code is giving the following error:

Any suggestion would be greatly appreciated. Thanks for your time.

Answer 1

TFF's recent releases have been compatible only with Python 3.9 and later; Google Colab's hosted runtimes are still on Python 3.7.

Likely the quickest way to run these notebooks is to run your own local runtime using Python 3.9, and connect the notebooks there; instructions on doing this from Colab can be found here .
