为什么在 Ubuntu 19.10 中安装 tensorflow-gpu 后 tensorflow 不起作用？

Question

我有一个 python 代码，它使用 tensorflow 进行机器学习

需要注意的重要一点是，在安装 tensorflow-gpu 之前，代码在 tensorflow 上运行良好。

安装 tensorflow-gpu 然后运行文件后出现以下错误

  File "fileName.py", line 1, in <module>
    import tensorflow as tf
  File "/home/<xyz>/.local/lib/python3.7/site-packages/tensorflow/__init__.py", line 41, in <module>
    from tensorflow.python.tools import module_util as _module_util
  File "/home/<xyz>/.local/lib/python3.7/site-packages/tensorflow/python/__init__.py", line 84, in <module>
    from tensorflow.python import keras
  File "/home/<xyz>/.local/lib/python3.7/site-packages/tensorflow/python/keras/__init__.py", line 27, in <module>
    from tensorflow.python.keras import models
  File "/home/<xyz>/.local/lib/python3.7/site-packages/tensorflow/python/keras/models.py", line 24, in <module>
    from tensorflow.python.keras import metrics as metrics_module

    populate_deserializable_objects()
  File "/home/<xyz>/.local/lib/python3.7/site-packages/tensorflow/python/keras/initializers/__init__.py", line 85, in populate_deserializable_objects
    generic_utils.populate_dict_with_module_objects(
AttributeError: module 'tensorflow.python.keras.utils.generic_utils' has no attribute 'populate_dict_with_module_objects'

使用 pip 成功安装了 tensorflow 和 tensorflow-gpu

使用pip show tensorflow检查 tensorflow 的安装

我还没有安装 CUDA 驱动程序。 这可能是问题吗？

Answer 1

此 GitHub 问题处理此问题。 这似乎与tf-nightly冲突。

尝试：

pip uninstall tf-nightly
pip install tensorflow --upgrade --force-reinstall # Or, tensorflow-gpu
