mratsim
A fast, ergonomic and portable tensor library in Nim with a deep learning focus for CPU, GPU and embedded devices via OpenMP, Cuda and OpenCL backends
#510 removed Travis and Appveyor and introduces Github Actions but the windows CI is blocked by Openblas/Lapack not being found in msys2 for some reason.
https://github.com/mratsim/Arraymancer/pull/510/checks?check_run_id=2980291716#step:21:823  The first failure may be due to rounding issue with float32 and switching to float64 will solve the issue. 1e-11 is way over float32 precision. https://github.com/mratsim/Arraymancer/blob/8514e78993ea5852eb8c4d45f00cfbf13b3e193f/tests/linear_algebra/test_linear_algebra.nim#L130-L147 The second...
I'm trying to use nim and arraymancer for a scientific project (and teach myself nim in the process). I stumbled across some inconsistency and I'm not sure if this is...

The generalized inverse of a Matrix defined by https://en.wikipedia.org/wiki/Moore%E2%80%93Penrose_inverse. The function is usually called ``pinv``(Numpy, Scipy, Julia LinAlg, Octave) sometime ``ginv`` (R). For reference : https://docs.scipy.org/doc/scipy/reference/generated/scipy.linalg.pinv.html (source : https://github.com/scipy/scipy/blob/v1.6.0/scipy/linalg/basic.py#L1288-L1305) I...

I was hoping to clarify what your long-term goal is for memory management. #150 suggests that you eventually want to add a `=sink` operator, but that seems to conflict with...
I know this would be a big job, but it would be really useful if the documentation could be organised better. Function documentation is organised by source file and it...
It would be handy to add indexing operators with return type `var Tensor[T]` so that the result can be passed to a function for in-place operations. This may relate to...
I was looking for a procedure similar to `numpy.where()` from python numpy but I cannot find it. So, I think it is beneficial to create a procedure that do this...
