尝试导入 tensorflow_probability 时出错（没有名为 keras 的模块）

Question

当我尝试导入 tensorflow_probability 时出现此错误：

Traceback (most recent call last):
  File "PATH", line 7, in <module>
    import tensorflow_probability as tfp
  File "PATH", line 20, in <module>
    from tensorflow_probability import substrates
  File "PATH", line 21, in <module>
    from tensorflow_probability.python.internal import all_util
  File "PATH", line 142, in <module>
    dir(globals()[pkg_name])  # Forces loading the package from its lazy loader.
  File "PATH", line 61, in __dir__
    module = self._load()
  File "PATH", line 44, in _load
    module = importlib.import_module(self.__name__)
  File "PATH", line 127, in import_module
    return _bootstrap._gcd_import(name[level:], package, level)
  File "PATH", line 35, in <module>

    module = self._load()

    module = importlib.import_module(self.__name__)
  File "PATH", line 127, in import_module
    return _bootstrap._gcd_import(name[level:], package, level)
ModuleNotFoundError: No module named 'keras'

我有最新版本的 tensorflow (2.6.0) 和 tensorflow_probability (0.14.0)，我什至单独安装了 keras（即使我认为 tensorflow 也包含 keras？）但我仍然收到此错误。如果重要的话，我也在使用 pycharm（带有 conda）。

tensorflow-probability 0.15.0 与 Tensorflow 2.7.0、Keras 2.7.0 和 Numpy 1.19.5 合作：

import tensorflow-probability
