Theano無法導入pygpu/cudnn（macOS，CUDA 8）

問題是我無法導入theano。我知道還有其他幾個關於同一問題的問題，但他們都沒有爲我工作，通常他們要麼與舊版本或不同的操作系統。我一直在努力解決這個問題，現在我已經嘗試了所有可以找到的解決方法和技巧，所以我無法想出其他任何東西來嘗試，而不是在這裏問問。Theano無法導入pygpu/cudnn（macOS，CUDA 8）

如果我嘗試python3 -c "import theano"沒有sudo，我得到如下：

ERROR (theano.gpuarray): Could not initialize pygpu, support disabled 
Traceback (most recent call last): 
    File "/Users/np/miniconda3/lib/python3.6/site-packages/theano/gpuarray/__init__.py", line 164, in <module>

    raise RuntimeError("error creating cudnn handle")

使用sudo，我得到

我知道這是動態鏈接一個問題，但我想不出爲什麼它不工作。

我曾嘗試以下：

禁用SIP
重新安裝CUDA和cudnn大概在10倍，現在
- cudnn文件是在這兩個/Developer/NVIDIA/CUDA-8.0/lib和/usr/local/cuda/lib
重新安裝了python，conda，theano，pygpu也是一個現在輪10倍
編譯libgpuarray
重啓幾次，以確保它不是那麼
執行的update_dyld_shared_cache，看它是否是一個緩存的問題
試圖與install_name_tool鏈接libcudnn.6.dylib到pygpu的.so的，但什麼也沒做

下面是.zshrc我的路徑：

export CUDA_HOME=/usr/local/cuda 
export DYLD_LIBRARY_PATH=/usr/local/cuda/lib:/usr/local/cuda/extras/CUPTI/lib 
export LD_LIBRARY_PATH=$DYLD_LIBRARY_PATH 
export PATH=$CUDA_HOME/bi:$DYLD_LIBRARY_PATH:$PATH

floatX = float32

我終於能夠通過將libcudnn *文件移動到/usr/lib來解決這個問題。我完全不知道爲什麼pygpu無法使用/usr/local/cuda/lib。沒有sudo我仍然得到RuntimeError: error creating cudnn handle錯誤，但現在它至少與sudo一起工作。

雖然現在我正在與Segmentation fault: 11戰鬥，但我猜這是一個不同的問題。 Theano是絕對的...
