Deep Dream：CPU有效但GPU不起作用，無法加載本機TensorFlow運行時

Question

我對此很陌生，因此如果我的術語不完美，我深表歉意，但是我做了很多嘗試和搜索，但無法解決這個問題。

我一直在嘗試創建深夢風格的圖像，以便可以批量處理視頻。

我已經嘗試了很多不同的東西，指南和版本，但無法在python 3.6.6或更高版本上安裝tensorflow。 但請遵循以下指南：

（ https://www.reddit.com/r/deepdream/comments/6z5tyz/guide_on_how_to_setup_neural_style_transfer_on/ ）

我終於讓它工作了，但只能作為張量流CPU使用。 這很棒，但是很慢，我有一個GTX 1080，我想充分利用它。

當我安裝Tensorflow-gpu時，它說工作正常

但是當我通過導入GPU版本進行測試時，得到以下信息：

Failed to load the native TensorFlow runtime.

See https://www.tensorflow.org/install/errors

for some common reasons and solutions.  Include the entire stack trace
above this error message when asking for help.

CPU工作的事實向我暗示了它與CUDA，cuDNN或Tensor flow GPU的版本有關，但是我已經嘗試過

Cuda 8(update2) + CuDNN 6
Cuda 8(update2) + CuDNN 5.1
Cuda 7.5 + cuDNN 5.1

再加上一大堆較新的 我相信我已經安裝了所有正確的依賴項。

我已經檢查了PATH，就像其他在這里遇到類似問題的人所建議的那樣，這似乎還不錯，所以我不知道從這里去哪里？

我為CPU工作，但是我需要能夠做數百個視頻工作，因此，非常感謝您的幫助。

更新：我發現這個不錯的小的自檢腳本，適用於1.4 鏈接之前的版本

這表示找不到我安裝，然后測試的cuDNN v6，仍然是相同的錯誤。 再次進行自我檢查並獲得此結果

C:\Users\kurti\Documents\Projects SSD\TESTS\Deep Dream>tensorflow_self_check.py
ERROR: Failed to import the TensorFlow module.

WARNING! This script is no longer maintained!
=============================================

Since TensorFlow 1.4, the self-check has been integrated with TensorFlow itself,
and any missing DLLs will be reported when you execute the `import tensorflow`
statement. The error messages printed below refer to TensorFlow 1.3 and earlier,
and are inaccurate for later versions of TensorFlow.

- Python version is 3.5.

- TensorFlow is installed at: C:\Users\kurti\AppData\Local\Programs\Python\Python35\lib\site-packages\tensorflow

- All required DLLs appear to be present. Please open an issue on the
  TensorFlow GitHub page: https://github.com/tensorflow/tensorflow/issues

更新2：

經過更多研究后，建議使用Anaconda，因為這顯然不太容易出現諸如Windows中的上述問題。 這些是我正在采取的步驟

1. conda創建-n [名稱] python = 3.5
2. 激活[名稱]
3. 康達安裝tensorflow-gpu
4. pip3安裝（numpy-1.16.2 + mkl-cp35-cp35m-win_amd64.whl）
5. pip3安裝（opencv_python-3.4.5-cp35-cp35m-win_amd64.whl）
6. pip3安裝（scipy-1.2.1-cp35-cp35m-win_amd64.whl）

當我輸入時，這不會給我任何錯誤

python
>>>import tensorflow
>>>import numpy

但是當我嘗試運行腳本（適用於cpu版本）時，它不再能找到numpy

    (tf2) C:\Users\kurti\GitProjects\DeepStyle\Deep Style\neural-style-tf-master>neural_style.py --content_img littleme.jpg --style_imgs starry-night.jpg --max_iterations 100 --verbose

  File "C:\Users\kurti\Anaconda3\lib\site-packages\tensorflow\python\__init__.py", line 47, in <module>
    import numpy as np
ModuleNotFoundError: No module named 'numpy'

運行pip3列表顯示numpy，運行pip列表顯示numpy，運行conda列表顯示錯誤的numpy，

我相信為所需的.whl運行pip3安裝不會將其安裝到我的conda環境中，這是否正確，我該如何解決？

Answer 1

我不確定這是否有幫助，但是Tensorflow安裝文檔建議Windows GPU版本僅適用於cuDNN64_7.dll ，因此我猜這是cuDNN v6？ 我僅提及此問題，因為該錯誤看起來找不到所需的.dll ，也許是cuDNN之一？ 文檔中還有一些有關如何設置路徑等的額外信息，請讓我知道如何進行。
