python - TensorFlow 导入错误

Question

我使用 pip install 安装了 Tensorflow 2.2.0，在 Python 3.8 中导入时遇到了一些问题。发生以下错误，我想知道如何解决此问题：

Traceback (most recent call last):
  File "C:\Program Files\Python38\lib\site-packages\tensorflow\python\pywrap_tensorflow.py", line 58, in <module>
    from tensorflow.python.pywrap_tensorflow_internal import *
  File "C:\Program Files\Python38\lib\site-packages\tensorflow\python\pywrap_tensorflow_internal.py", line 28, in <module>
    _pywrap_tensorflow_internal = swig_import_helper()
  File "C:\Program Files\Python38\lib\site-packages\tensorflow\python\pywrap_tensorflow_internal.py", line 24, in swig_import_helper
    _mod = imp.load_module('_pywrap_tensorflow_internal', fp, pathname, description)
  File "C:\Program Files\Python38\lib\imp.py", line 242, in load_module
    return load_dynamic(name, filename, file)
  File "C:\Program Files\Python38\lib\imp.py", line 342, in load_dynamic
    return _load(spec)
ImportError: DLL load failed while importing _pywrap_tensorflow_internal: The specified module could not be found.

During handling of the above exception, another exception occurred:

根据GitHub上这个问题的官方线程，这个问题显然有两种解决方案：

第一个解决方案：

从更简单的解决方案开始，您可以尝试将您的tensorflow版本降级为2.0.0喜欢的版本。要安装此版本，您至少需要pip 20.1：

# update pip first
pip install -U pip

# install tensorflow 2.0 
pip install tensorflow==2.0

第二种解决方案：

如果第一个解决方案不适合您，那么您可以分别从此处和此处下载并安装新的 C++ 可再发行 x86 和 x64 包。
