Question

问题是我无法导入theano。我知道有关于同一问题的其他几个问题，但它们都没有对我有用，通常它们是旧版本或不同操作系统。我一直试图解决这个问题几天，我已经尝试了所有可以找到的修复和技巧，所以我无法想出任何其他的东西来尝试，而不是在这里问。

如果我在没有sudo的情况下尝试python3 -c "import theano"，我会得到以下内容：

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")
RuntimeError: error creating cudnn handle

sudo我得到了

我知道这是动态链接的问题，但我无法弄清楚它为什么不起作用。

我尝试了以下内容：

已禁用SIP
现在重新安装CUDA和cudnn大约10次
- cudnn文件同时包含/Developer/NVIDIA/CUDA-8.0/lib和/usr/local/cuda/lib
现在重新安装了python，conda，theano，pygpu大约10次
从头开始编译libgpuarray
重新启动几次以确保它不是那个
已执行update_dyld_shared_cache以查看是否为缓存问题
尝试将libcudnn.6.dylib与install_name_tool链接到pygpu .so但是没有做任何事情

以下是来自.zshrc的路径：

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

[global]
floatX = float32
device = cuda
force_device = True
allow_gc = False
optimizer_including=cudnn

[cuda]

[dnn]

版本号：

CUDA 8.0和cudnn 6.0
Python 3.6.1
Theano 0.9.0
libgpuarray 0.6.4
pygpu 0.6.4

Answer 1

我终于能够通过将libcudnn *文件移动到/usr/lib来解决这个问题。我完全不知道为什么pygpu无法使用/usr/local/cuda/lib。没有sudo，我仍然会收到RuntimeError: error creating cudnn handle错误，但现在它至少可以使用sudo。

虽然现在我和Segmentation fault: 11打架，但我猜这是一个不同的问题。 Theano绝对是......

Theano无法导入pygpu / cudnn（macOS，CUDA 8）
