Detectron2 does not install due to grpcio error

I am trying to install Detectron2 on a computation cluster and receive the following error regarding grpcio. Please note that I have already installed PyTorch 1.3, TorchVision and other dependencies.

Collecting grpcio>=1.24.3 (from tensorboard->detectron2==0.1)
Could not find a version that satisfies the requirement grpcio>=1.24.3 (from tensorboard->detectron2==0.1) (from versions: 1.11.0, 1.12.1, 1.13.0, 1.15.0, 1.16.0, 1.16.1, 1.17.1)
No matching distribution found for grpcio>=1.24.3 (from tensorboard->detectron2==0.1)

Has any one else encountered this issue?

From pip, it looks like the latest version is 1.25.
So you should be able to find it. Not sure why you don’t see it as an option. Maybe upgrade pip?

Thanks for your response.
My pip is up to date, although I re-checked it. It runs the 18.1 version.
I checked the version of grpcio by trying to install using pip, and it seems to be running grpcio 1.17.1 and this might be the problem. I’ll try updating grpcio and see where it takes me.
