Hi,
yesterday I read the message about the new CUDA package. Today I just did an update (julia 1.6.0 on ubuntu mate 20.04) and the CUDA package did upgrade. After that
julia> using CUDA
julia> CUDA.zeros(10)

ERROR: CUDA.jl did not successfully initialize, and is not usable.
If you did not see any other error message, try again in a new session
with the JULIA_DEBUG environment variable set to ‘CUDA’
etc…
Needless to say. it was perfectly working until the second before the update, nothing changed in my system. In fact I ran a julia code using CUDA and did the update after the run finished.
What can I do from here? And since I need to do calculations in my computer, can I revert to the previous CUDA version in the meantime? How?
Thanks a lot,
Ferran.
