ubuntu-16.04 - 在 $PATH 上找不到 nvcc 编译器

Question

我在使用 theano 时收到以下错误：

错误（theano.sandbox.cuda）：在 $PATH 上找不到 nvcc 编译器。检查您的 nvcc 安装并重试。

我已经尝试了之前问题给出的所有解决方案。运行nvcc -V返回以下内容：

nvcc: NVIDIA (R) Cuda compiler driver
Copyright (c) 2005-2017 NVIDIA Corporation
Built on Fri_Nov__3_21:07:56_CDT_2017
Cuda compilation tools, release 9.1, V9.1.85

并which nvcc返回以下内容：

/usr/local/cuda-9.1/bin//nvcc

我还确认我有一个 nvcc 文件/usr/local/cuda-9.1/bin。

我运行了以下命令以确保可以找到 nvcc：

export PATH=/usr/local/cuda-9.1/bin/:$PATH
export LD_LIBRARY_PATH=/usr/local/cuda-9.1/lib64:$LD_LIBRARY_PATH
exec bash

我已经确认 nvcc 位置肯定在 $PATH 中，因为运行echo $PATH返回以下内容：

/home/paperspace/anaconda3/bin:/home/paperspace/src/torch/install/bin:/home/paperspace/src/torch/install/bin:/home/paperspace/anaconda3/bin:/home/paperspace/src/torch/install/bin:/home/paperspace/src/torch/install/bin:/usr/local/cuda-9.1/bin/:/usr/local/cuda-9.1/bin/:/home/paperspace/anaconda3/bin:/home/paperspace/src/torch/install/bin:/home/paperspace/src/torch/install/bin:/home/paperspace/anaconda3/bin:/home/paperspace/src/torch/install/bin:/home/paperspace/src/torch/install/bin:/home/paperspace/anaconda3/bin:/home/paperspace/src/torch/install/bin:/home/paperspace/src/torch/install/bin:/home/paperspace/anaconda3/bin:/home/paperspace/src/torch/install/bin:/home/paperspace/src/torch/install/bin:/home/paperspace/anaconda3/bin:/home/paperspace/src/torch/install/bin:/home/paperspace/src/torch/install/bin:/home/paperspace/anaconda3/bin:/home/paperspace/src/torch/install/bin:/home/paperspace/src/torch/install/bin:/usr/local/cuda/bin/:/home/paperspace/src/torch/install/bin:/home/paperspace/bin:/home/paperspace/anaconda3/bin:/home/paperspace/src/torch/install/bin:/home/paperspace/src/torch/install/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin:/usr/lib/jvm/java-9-oracle/bin:/usr/lib/jvm/java-9-oracle/db/bin:/usr/local/cuda/bin:/usr/local/cuda/bin:/usr/local/cuda/bin:/usr/local/cuda/bin:/usr/local/cuda/bin:/usr/local/cuda/bin:/usr/local/cuda/bin:/usr/local/cuda/bin:/usr/local/cuda/bin

此外，如果我打开一个 python 控制台并运行，import os; print(os.environ["PATH"])我会得到以下信息（同样的事情）：

/home/paperspace/anaconda3/bin:/home/paperspace/src/torch/install/bin:/home/paperspace/src/torch/install/bin:/home/paperspace/anaconda3/bin:/home/paperspace/src/torch/install/bin:/home/paperspace/src/torch/install/bin:/usr/local/cuda-9.1/bin/:/usr/local/cuda-9.1/bin/:/home/paperspace/anaconda3/bin:/home/paperspace/src/torch/install/bin:/home/paperspace/src/torch/install/bin:/home/paperspace/anaconda3/bin:/home/paperspace/src/torch/install/bin:/home/paperspace/src/torch/install/bin:/home/paperspace/anaconda3/bin:/home/paperspace/src/torch/install/bin:/home/paperspace/src/torch/install/bin:/home/paperspace/anaconda3/bin:/home/paperspace/src/torch/install/bin:/home/paperspace/src/torch/install/bin:/home/paperspace/anaconda3/bin:/home/paperspace/src/torch/install/bin:/home/paperspace/src/torch/install/bin:/home/paperspace/anaconda3/bin:/home/paperspace/src/torch/install/bin:/home/paperspace/src/torch/install/bin:/usr/local/cuda/bin/:/home/paperspace/src/torch/install/bin:/home/paperspace/bin:/home/paperspace/anaconda3/bin:/home/paperspace/src/torch/install/bin:/home/paperspace/src/torch/install/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin:/usr/lib/jvm/java-9-oracle/bin:/usr/lib/jvm/java-9-oracle/db/bin:/usr/local/cuda/bin:/usr/local/cuda/bin:/usr/local/cuda/bin:/usr/local/cuda/bin:/usr/local/cuda/bin:/usr/local/cuda/bin:/usr/local/cuda/bin:/usr/local/cuda/bin:/usr/local/cuda/bin

我在 /home/paperspace 中的 .theanorc 文件如下：

[global]
device = cuda
floatX = float32
[cuda] 
root = /usr/local/cuda-9.1
