我在 python2.7.11 中有一个使用chainer 和cupy 的项目。将 Chainer 版本从 1.22 更新到 4.1.0 后,我无法使用 cupy
>>> import cupy
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: No module named cupy
这是我安装chainer1.22的方式。无需安装cupy即可成功导入cupy。
pip install chainer==1.22,
查看
>>> import chainer
>>> import cupy
>>> chainer.cuda.available
True
我可以看到 CUDA 可用于chainer1.22
所以我卸载了chainer 1.22
pip uninstall chainer
安装chainer 4.1.0
pip install chainer==4.1.0
结果是
>>> import chainer
>>> import cupy
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: No module named cupy
>>> chainer.cuda.available
False
可以看到 cuda 不适用于 chainer 版本 4.1.0。所以我尝试用 pip 安装 cupy
pip install cupy
安装时记录

无法构建 cupy 我检查了 nvcc 版本
nvcc -V

当我尝试在chainer1.22环境下通过pip安装cupy时,也会出现同样的问题
这是我的环境

我引用了这篇文章 ,但它对我不起作用。
如何使用 CHAINER4.1.0 导入 CUPY?
