Example from README.md fails

[lruthotto]

I'm looking for a julia way to do FFTs on the GPU and tried the example from the README.md page, which failed. Couldn't find the problem in the code, so maybe someone else can help. Thanks !

julia> CUDArt.devices(dev->capability(dev)[1] >= 2, nmax=1) do devlist
           A = rand(7,6)
           # Move data to GPU
           G = CudaArray(A)
           # Allocate space for the output (transformed array)
           GFFT = CudaArray(Complex{eltype(A)}, div(size(G,1),2)+1, size(G,2))
           # Compute the FFT
           pl! = plan(GFFT, G)
           pl!(GFFT, G, true)
           # Copy the result to main memory
           AFFTG = to_host(GFFT)
           # Compare against Julia's rfft
           AFFT = rfft(A)
           @test_approx_eq AFFTG AFFT
           # Now compute the inverse transform
           pli! = plan(G,GFFT)
           pli!(G, GFFT, false)
           A2 = to_host(G)
           @test_approx_eq A A2/length(A)
       end

My OS is ubuntu, CUDA driver are up to date and here is more about my julia version:

I have the same problem, Pkg.test("CUFFT") fails with "UndefVarError: uint8 not defined".
