> In NumPy 1.20.0, they [deprecated a series of aliases](https://numpy.org/devdocs/release/1.20.0-notes.html#deprecations). I believe that the argument for deprecating inbuilt types in NumPy is a bit stronger since it was know for...

I contacted the authors by e-mail and received a link to the dataset and can confirm that the alpha mattes are of very high quality. The subjects are mostly people,...

## 2) Writable views Writing to the diagonal of a matrix with `np.einsum` still works for me. Perhaps you wrote `diagonal = ...` instead of `diagonal[:] = ...`? The later...

I thought so, too. I read the docs now and apparently almost the same example can be found further down the page. Maybe it is possible to link from the...

Compiling and running with address sanitizer does not raise any issues: ```bash gcc -g -fsanitize=address -fsanitize=undefined -pipe -Wall -O3 -fomit-frame-pointer -march=native -std=c99 -mfpmath=sse -msse3 -fopenmp fasta.gcc-2.c -o fasta.gcc-2.gcc_run && ./fasta.gcc-2.gcc_run...

This optimization will probably become irrelevant with the [new string dtype](https://numpy.org/neps/nep-0055-string_dtype.html), so I think this is not worth pursuing anymore.

There only is GPU support for foreground estimation, but not for alpha matting itself. For foreground estimation, simply install [PyOpenCL or CuPy](https://github.com/pymatting/pymatting/blob/master/requirements_gpu.txt) and import the relevant foreground estimation method https://github.com/pymatting/pymatting/blob/b5f03a2c373cfe3ca6ba0f69a56e113ca3c5807d/tests/test_foreground.py#L13...
