Hello! I am trying to use julia's CUDA package in Python, however I run into troubles.
The code that I run is following:
from julia.api import Julia
import juliapkg as pkg
executable = pkg.executable()
jl = Julia(runtime=executable) # , compiled_modules=False)
jl.eval('''
import Pkg
Pkg.add("CUDA")
using CUDA
function gpu_compute()
return CUDA.rand(Float16, 2, 2) * CUDA.rand(Float16, 2, 2)
end
''')
result = jl.eval('gpu_compute()')
print(result)
and I run it using python-jl.
The output that I get is a SEGFAULT:
signal (11): Segmentation fault
in expression starting at none:4
unknown function (ip: (nil))
Allocations: 2904 (Pool: 2894; Big: 10); GC: 0
Segmentation fault (core dumped)
When I replace line 5: jl = Julia(runtime=executable) # , compiled_modules=False) with jl = Julia(runtime=executable , compiled_modules=False) and run it simply with Python I get:
Reason: unsupported dynamic function invocation (call to pointerset(ptr::Core.LLVMPtr{T, A}, x::T, i::I, ::Val{align}) where {T, A, I, align} @ LLVM.Interop ~/.julia/packages/LLVM/RFlwq/src/interop/pointer.jl:46)

Hint: catch this exception as `err` and call `code_typed(err; interactive = true)` to introspect the erronous code with Cthulhu.jl' occurred while calling julia code:
gpu_compute()
How can I get CUDA to work here?
