`cispi` has poor performance

5

Hi! `cispi` seems to have type infereability issues: ```julia f1(x) = sum(abs2, cispi.(x)) f2(x) = sum(abs2, cis.(x)) @time Zygote.gradient(f1, ones((1024,1024))) # 1.121823 seconds (18.87 M allocations: 648.002 MiB, 31.55% gc...

`abs2` of complex CUDA array fails with `Zygote.gradient`

7

Hey, when applying `abs2` to a complex CUDA array I get an `ERROR: MethodError: no method matching iterate(::Nothing)`. I'm using CUDA 3.1.0, Julia 1.6.1 and Zygote 0.6.10. But I also...

PyCall together with ImageView crashes

Hey, I encountered the following crash: ```bash julia> begin using ImageView using PyCall end julia> begin pygui_start(:qt5) qapp_obj = pyimport("qtpy.QtWidgets").QApplication([""]) end signal (11): Segmentation fault in expression starting at none:0...

Segmentation fault with threaded FFTW `FFTW.set_num_threads(n)` and `julia --threads=k` where `k, n > 1`

1

Hey, I noticed that threaded FFTW.jl (1.0, 1.1, 1.3, 1.4) with Julia (1.6.1, 1.5.4) seems to crash with segmentation faults on my machine (AMD Ryzen 5 5600x). I have no...

Unable to infer range of index which occurs two times

```julia # works function bin(x, Δ=0::Int) @tullio res[i] := x[i + 0] + x[i + Δ + 1] end # does not function bin2(x, Δ=0::Int) @tullio res[i] := x[i +...

`\sqrt` is not correctly detected for gradient

Hey, just the minor issue here: ```julia julia> using Zygote, Tullio julia> f(x) = @tullio r = √(x[i]^2 ) f (generic function with 1 method) julia> h(x) = @tullio r...

When supplied range conflicts with un-shifted index...

Hey, the following one: ```julia julia> using Tullio julia> y = ^C julia> y = (1:10) .* (1:10)' 10×10 Matrix{Int64}: 1 2 3 4 5 6 7 8 9 10...

Gradient missing for `begin ... end`

```julia julia> f1(x) = sum(@tullio res[i, j] := begin x[i+2, j] - 2 * x[i+1, j] + x[i, j] end) f1 (generic function with 1 method) julia> gradient(f1, x) ERROR:...

How to implement n-dimensional functions?

11

Hey, I'm trying to figure out how we could use Tullio to generalize some n-dimensional functions. Let's say I've got a n-dimensional array and I want to use Tullio for...

Pluto & PyPlot.jl `imshow`

1

Hey, I've seen that `PyPlot.jl` in general works, but in Pluto nothing really happens for: ```julia begin using PyPlot PyPlot.imshow(randn((3,3))) end ``` Only some output: ```julia PyObject ``` In the...
