无法加载本机 tensorflow 运行时

Question

我一直在使用 tensorflow（通过 Keras）来完成一些简单的图像分类任务。 它在去年年底（12 月中旬）运行良好，但现在我已经完成了一些包更新并在尝试运行我的代码时出现此错误：

Traceback (most recent call last):
  File "C:\Python\lib\site-packages\tensorflow_core\python\pywrap_tensorflow.py", line 58, in <module>
    from tensorflow.python.pywrap_tensorflow_internal import *
  File "C:\Python\lib\site-packages\tensorflow_core\python\pywrap_tensorflow_internal.py", line 28, in <module>
    _pywrap_tensorflow_internal = swig_import_helper()
  File "C:\Python\lib\site-packages\tensorflow_core\python\pywrap_tensorflow_internal.py", line 24, in swig_import_helper
    _mod = imp.load_module('_pywrap_tensorflow_internal', fp, pathname, description)
  File "C:\Python\lib\imp.py", line 242, in load_module
    return load_dynamic(name, filename, file)
  File "C:\Python\lib\imp.py", line 342, in load_dynamic
    return _load(spec)
ImportError: DLL load failed: The specified module could not be found.

During handling of the above exception, another exception occurred:

很自然地会怀疑某些软件包更新破坏了某些东西，但我不确定它可能是哪一个。 我拥有 tensorflow (2.1.0) 和 Keras (2.3.1) 的（当前）最新版本。 我正在使用带有英特尔 i5-7200U CPU 的 Windows 10 PC。 我没有使用 tensorflow-gpu，因为我在没有专用 gpu 的笔记本电脑上运行这个小任务，如果有帮助的话。

谁能帮我弄清楚发生了什么变化？ 谢谢！

此问题的常见解决方案是您需要从此处安装/更新 Microsoft Visual C++ 2015-2019 Redistributable (x64)
