python - 无法导入 tensorflow_probability

Question

当我尝试导入 tensorflow_probability 时，出现此错误:

Traceback (most recent call last):
  File "PATH", line 1, in <module>
    import tensorflow_probability
  File "PATH", line 75, in <module>
    from tensorflow_probability.python import *  # pylint: disable=wildcard-import
  File "PATH", line 24, in <module>
    from tensorflow_probability.python import edward2
  File "PATH", line 32, in <module>
    from tensorflow_probability.python.experimental.edward2.generated_random_variables import *
  File "PATH", line 34, in <module>
    from tensorflow_probability.python.experimental import auto_batching
  File "PATH", line 24, in <module>
    from tensorflow_probability.python.experimental.auto_batching import frontend
  File "PATH", line 46, in <module>
    from tensorflow.python.autograph.pyct import compiler
ImportError: cannot import name 'compiler' from 'tensorflow.python.autograph.pyct' (PATH)

我不知道为什么 Python 不能导入这个模块，因为当我在 cmd 中输入 pip list 时，它告诉我我有 tensorflow-probability 0.8.0rc0 安装。任何帮助将不胜感激。

尝试安装 tf_agents 包。尝试导入 tensorflow_probability 时出现一些导入错误。这些包括:

• 模块“tensorflow.python.ops.linalg.linear_operator”没有属性“make_composite_tensor”
• 无法从“tensorflow_probability.python.internal”导入名称“all_util”。

当我安装并导入 tf_agents 时，这些问题得到了解决。

pip install --upgrade tf_agents

如果您使用的是 jupyter，请将以下内容添加到单元格中，然后运行它:

import sys
!{sys.executable} -m pip install --upgrade tf_agents
