无法从“tensorflow.compat.v2.experimental”导入名称“dtensor”

Question

我尝试在 Windows 10 计算机上运行 TensorFlow 时遇到问题。代码在我的 MacOS 机器上运行良好。

Answer 1

这可能是由于您tensorflow和您的keras版本之间不兼容造成的。特别是我在tensorflow==2.6.0and中看到了这一点keras==2.9.0，但如果其他版本也能导致这种情况，我不会感到惊讶。

通过以下方式更新您的tensorflow版本：

pip install tensorflow==2.8

或keras通过以下方式降级您的版本：

pip install keras==2.6

我尝试了很多解决方案都没有效果，最后这个对我有用！

pip3 uninstall tensorflow absl-py astunparse flatbuffers gast google-pasta grpcio h5py keras keras-preprocessing libclang numpy opt-einsum protobuf setuptools six tensorboard tensorflow-io-gcs-filesystem termcolor tf-estimator-nightly typing-extensions wrapt

pip3 install --disable-pip-version-check --no-cache-dir tensorflow
