arrayfire-python conflict with pycuda on anaconda with Linux

该失败通过 arrayfire/tests/simple/array_test.py 和 arrayfire/tests/simple/_util.py 报告，格式化位于 arrayfire/array.py，错误处理位于 arrayfire/util.py。复现安装了 pycuda 的 Anaconda/Linux 环境，然后将其与 separate-PYTHONPATH 这一变通方案进行比较。当 simple 测试无需该变通方案即可通过，并且依赖项交互已记录或修复时，即视为完成。

Hi,

I am using anaconda on linux, I have been previously using arrayfire on windows fine. I installed latest arrayfire on the Linux OS.. The error was

ERROR:root:Traceback (most recent call last):

After spending a day trying to think as to what the problem could be, I discovered that the problem is due to conflict with the install of pycuda, as soon as I removed pycuda, the arrayfire tests passed. The different version of pycuda give the same error.

Now I solved the issue by installing pycuda in a separate folder and adding that to the PYTHONPATH instead of the default in anaconda.
