Tensorflow 2.4 - DLL 在導入 _pywrap_tensorflow_internal 時加載失敗

Question

I use TensorFlow 2.4 on Windows 10 with Python 3.8 (I have Python 3.9 and 3.6 installed too) within a virtual environment ml2u where only TensorFlow 2.4 is installed so far by pip install tensorflow . 我通過嘗試在筆記本中導入 TensorFlow 收到以下錯誤消息。 正如其他帖子中所推薦的那樣，我已經安裝了 Microsoft Visual C++ redistributable，這導致了 MS Visual 和VC_redist.x64.exe的安裝。

import tensorflow as tf

During handling of the above exception, another exception occurred:

您可能會遇到此問題，因為您正在運行 32 位 python 或 32 位操作系統。 並檢查您的 CPU 是否支持 AVX 指令。

請查看系統要求並檢查您是否安裝了正確的依賴項。
