I just moved from the deprecated CuArrays package to CUDA. I used `add CUDA` and `status` tells me v0.1 is installed. The most recent release is v1.1.0.

Am I doing something wrong ? Maybe I have to uninstall stuff before ?

What version of Julia are you using? I think `CUDA.jl` requires Julia v1.3 or later versions

If you do `add CUDA@1.1.0` it should tell you the conflict preventing the upgrade (granted it can sometimes be hard to decipher).

So it’s a compatibility issue

As a general recommendation: use local environments for your projects and keep as few packages as possible in the global environment. This will drastically reduce the rate of these issues (and using local environments is a good thing for reproducibility anyway). It’s just impossible to install all packages you may want in a single huge environment without running into compatibility issues.

If you don’t want to follow the above recommendation, try at least to remove non-important packages and update the registry, to relax some constraints

Okay, removing CUDAdrv, CUDAnative and CuArrays was necessary. Now everything seems to be in order.

Thank you for your help

I don’t understand, this list I posted is from my project environment. I have almost no package in my global environment I think. Is that a problem you think ? I want people to be able to reproduce the experiments using `instantiate`.
