Windows Bash Run Chainerrl unknown cuda error

[tigerneil]

recently I got a windows 10 computer, successfully installed bash on ubuntu for windows, cuda, cudnn, chainer and chainerrl. But to run the example, I got the following error. Any suggestions?

Can you successfully use chainer with gpu, say https://github.com/pfnet/chainer/blob/master/examples/mnist/train_mnist.py with -g 0?

This is the result in ipython

It seems like you failed to install chainer or cuda. Did you successfully install cuda? Did you follow https://github.com/pfnet/chainer#installation-with-cuda when installing chainer?

[tigerneil]

it seems like bash for windows is not good. I can't make gpu driver work well. I will check it later. Close it first. Thanks.
