我试图导入这个

from tensorflow.keras import Sequential
from tensorflow.keras.layers import Conv2D, Flatten, Dense
from tensorflow.keras.callbacks import EarlyStopping

我收到了这个错误：

TypeError: Expected a message Descriptor, got Descriptor

我不知道为什么它在以前很好的时候突然这样做了。我为那些遇到“预期字节”错误的人尝试了解决方案，但无济于事。似乎以前没有人遇到过这个错误。

非常感谢您的帮助！

【问题讨论】：

你能提供更多细节吗？你在 GPU 上使用 TensorFlow 吗？您是否尝试在虚拟环境中执行此操作？像康达？您在系统上安装了什么版本的 TensorFlow？
@ARAT 1. 是的，我在 GPU 上使用它。 2. 使用 Anaconda3 的 Jupyter Notebook 时出现错误。 3. 我使用的是 2.4.1 版本。谢谢！
您的 tensorflow 安装似乎已损坏。尝试卸载现有版本并安装新版本pip install tf-nightly。此外，您可能还需要pip install protobuf

标签： python python-3.x tensorflow keras

【解决方案1】：

这对我有用！

卸载 TensorFlow 并重新安装（对我来说是 tensorflow==1.0.1）
pip install protobuf==3.6
