下面的代码给出了一个错误消息。我该如何解决这个问题?显示图形执行错误。面部情绪检测问题。
history = model3.fit(x= train_set, validation_data = validation_set, batch_size = 32, epochs = 20)
错误:

安装tensorflow版本2.7它应该为你工作，我有同样的问题，并通过安装和使用tensorflow版本2.7得到了解决方案。
安装过程:
pip install tensorflow==2.7
in collab:
!pip install tensorflow==2.7
如果您正在使用m1，请卸载tensorflow-metal!这两行就够了
conda install -c apple tensorflow-deps==2.5.0
python3 -m pip install tensorflow-macos==2.5.0
