导入tensorflow时出错:ImportError: DLL load failed: 找不到指定的模块

问题如上，控制台回显如下，我看网上说是第三方库安装不完整，或者安装的第三方库被覆盖或者破坏，但是我看不出是哪个库出错了

Failed to load the native TensorFlow runtime.

看起来像是由于缺少某个库导致了DLL加载失败。以下是一些可能的解决方案：

检查您的环境变量。如果您已经安装了TensorFlow并且正在尝试在新的Python环境中导入它，那么您需要确保将TensorFlow的路径添加到新环境的系统变量中。您可以通过在命令行中运行以下命令来检查TensorFlow的路径：

python -c "import tensorflow; print(tensorflow.file)"
这将打印出TensorFlow的路径，您可以将其添加到新环境的系统变量中。

重新安装TensorFlow。如果您已经安装了TensorFlow并且尝试在新的Python环境中导入它，那么您需要确保您的安装是完整的，没有被覆盖或者破坏。您可以尝试卸载并重新安装TensorFlow，以确保它与您的Python环境兼容。请注意，这可能会影响到您的其他库。

检查您的第三方库。如果上述解决方案都不起作用，那么您可能需要检查您的第三方库是否完整。您可以尝试运行以下命令来查找并安装任何缺失的库：

pip freeze
这将打印出当前已安装的所有库及其版本。然后，您可以搜索并安装任何缺失的库，例如：

pip install numpy==1.19.5

不知道你这个问题是否已经解决, 如果还没有解决的话:

这篇文章讲的很详细，请看：导入tensorflow报错：ImportError: DLL load failed: 找不到指定的模块
除此之外, 这篇博客: 导入tensorflow包报错——ImportError: DLL load failed: 找不到指定的模块中的 一、运行报错 部分也许能够解决你的问题, 你可以仔细阅读以下内容或者直接跳转源博客中阅读:
执行导入包命令
```
import tensorflow as tf
```
报错显示如下

找不到指定模块，于是尝试解决，以下是漫长的解决历史。
以下回答来自chatgpt:
解决方案：根据参考资料中的段落1，尝试将protobuf版本回退到3.6.0，使用以下命令： pip install protobuf==3.6.0 如果还是不能解决问题，可以按照参考资料中的段落6，下载并安装vc_redist应用程序来获取必要的msvcp140_1.dll文件。如果以上两种方法都不能成功解决问题，可以重新检查自己安装的第三方库是否完整，并试着重新安装或升级缺失或损坏的库。

如果你已经解决了该问题, 非常希望你能够分享一下解决方案, 写成博客, 将相关链接放在评论区, 以帮助更多的人 ^-^
