Unsupported operation when using CUDA #1532
Description
Motivation and description
The attached is actually a jupyter notebook, but I saved with a .txt extension to upload.
In summary, I defined two functions
f₁(x) = sum(abs2, exp.(log.(x) .* (1:length(x))))
f₂(x) = sum(abs2, x.^(1:length(x)))
Their gradients agree on the CPU. When the argument is on the GPU, the first function's gradient is consistent with the CPU calculation, the later function throws an exception.
Possible Implementation
