TypeError: create_convolution_descriptor() got an unexpected keyword argument 'group'

[iaroslav-ai]

I am not able to run training with progressive gan code.
After installing chainer from source according to instructions here and following the instructions for installation in this repo, I try to run progressive gan training code as follows:

python3 train.py

However, I get an exception, which reads as:

Exception in main training loop: create_convolution_descriptor() got an unexpected keyword argument 'group'

Will finalize trainer extensions and updater before reraising the exception.

My OS: Ubuntu 16
I use python3
CuDNN version according to chainer.backends.cuda.cuda.cudnn.getVersion(): 7004
Cuda version according to nvcc --version: V8.0.61
cupy version: 3.0.0a1
numpy version: 1.14.0

Let me know if you need more information or if the issue should be posted in the chainer repo instead.

I installed cupy from source as described here and now it works! 🎉
Would you like a PR with a note about more recent version of dependencies for the progressive GAN?
