什么原因導致 Tensorflow 導入錯誤：DLL 加載失敗？

Question

I am using Anaconda environment on Windows 10. I have installed tensorflow-gpu using pip and when I try to import tensorflow, I get this import error below. 我嘗試使用 tensorflow 的 cpu 版本並使用新的 conda 環境重新安裝所有軟件包。 我的 python 是 3.7 版和 tensorflow-gpu 2.1.0 版。

    >>> import tensorflow as tf
Traceback (most recent call last):
  File "C:\Users\ossik\anaconda3\envs\tensorflow-gpu\lib\site-packages\tensorflow_core\python\pywrap_tensorflow.py", line 58, in <module>

Failed to load the native TensorFlow runtime.

您知道導致此錯誤的原因嗎？

Answer 1

• 嘗試降級並安裝 tensorflow。

pip install tensorflow==2.0

• 如果您使用 gpu

pip install --upgrade tensorflow-gpu==2.0

• 或嘗試下載這些 Visual Studio 文件單擊此處

Answer 2

這可能是因為您的 CPU（可能是舊的）不支持 AVX 指令（例如，Intel Pentium 或類似的）。 您可以使用以下方法解決此問題：

pip3 uninstall tensorflow

Go 此處： 與已使用 SSE2 指令預編譯的 tensorflow 2.1.0 車輪鏈接。

將wheel下載到您的項目，然后使用pip install <filename.wheel>安裝 tensorflow。 再試一次 - 錯誤應該得到解決
