Please help me!
First of all, thanks 4 Ur code which is fantastic!
However, I get a problem when I try to use gpu.
It shows that:
simon@John:~/Object_Detection/chainer-simple-fast-rnn-master$ python forward.py --img_fn sample.jpg --out_fn result.jpg --gpu_id 0

Traceback (most recent call last):
File "forward.py", line 152, in
xp = cuda.cupy
AttributeError: 'module' object has no attribute 'cupy'

but it okay when I using cpu.
Please help me handling this problem, THX.

I guess this is the error comes from chainer's settings. Did you install chainer with GPU enabled?

Try official Mnist example with GPU:
https://github.com/pfnet/chainer/tree/master/examples/mnist
python train_mnist.py --gpu 0

If this did not work, please contact chainer's support. If it worked, let's work together to solve the issue.
