Marco, My -1 vote is for dropping support to CUDA 8 and not for adding CUDA 9. CUDA 9.0 support for MXNet was added Oct'30-2017, I think that all users might not have switched to CUDA 9.0
Look at the earlier discussion on the same topic https://lists.apache.org/thread.html/27b84e4fc0e0728f2e4ad8b6827d7f996635021a5a4d47b5d3f4dbfb@%3Cdev.mxnet.apache.org%3E On Wed, Mar 14, 2018 at 10:14 AM, Marco de Abreu < [email protected]> wrote: > Right, the code changes would not be validated against CUDA 8.0 as part of > the PR process. > > I don't have any numbers, but it's pretty unlikely that anybody is still > using CUDA 8.0.
