Question

我正在尝试解开CudaNdarray，我收到导入错误。我知道我需要在一台带有GPU的机器上，所以我四处搜索并找到this BitFusion ec2 instance，据说它有GPU支持以及cuda。我下载了代码的所有依赖项，但我得到了这个：

File "predictor.py", line 112, in <module>
    predict = loadModel(filePath = '2_21_dim20000PREDICT113000.save')
  File "predictor.py", line 91, in loadModel
    model = pickle.load(file2open, encoding='latin1')
  File "/home/ubuntu/anaconda3/lib/python3.5/site-packages/theano/sandbox/cuda/type.py", line 591, in CudaNdarray_unpickler
    raise ImportError("Cuda not found. Cannot unpickle CudaNdarray")
ImportError: Cuda not found. Cannot unpickle CudaNdarray

这是我的代码（Python3）：

import os
import sys
import pickle
from random import shuffle
from copy import copy

def loadModel(filePath):
    file2open = open(filePath, 'rb')
    model = pickle.load(file2open, encoding='latin1')
    b.encode("latin1")
    file2open.close()
    return zlib.decompress(b)

predict = loadModel(filePath = '2_21_dim20000PREDICT113000.save')

我可以尝试一些事情：

A）确保安装了Cuda工具包：

conda list | grep cudatoolkit

如果您没有看到它，请尝试以下操作：

conda install cudatoolkit

python
>>> from numbapro import cuda
>>> cuda.is_available()
True
>>> cuda.__file__
'/home/ubuntu/anaconda3/envs/snowflakes/lib/python3.5/site-packages/numba/cuda/__init__.py'

B）你是否需要在Theano下导入CUDA包？

python
>>> from theano.sandbox import cuda
>>>cuda.cuda_path
'/home/ubuntu/anaconda3/envs/snowflakes/lib/python3.5/site-packages/theano/sandbox/cuda'
