Wrong blis version on Termux

[Manamama]

When installing spacy on Termux, the dependencies chain kept failing with your thinc.

When looking closer :

i realzed that it is because of the too strict version of blis in your requirements.

This blis installs "natively" in Termux:

~/downloads/spaCy $ pip show blis
Name: blis
Version: 0.9.1
Summary: The Blis BLAS-like linear algebra library, as a self-contained C-extension.
Home-page: https://github.com/explosion/cython-blis

Advice: be less restrictive in these.

i realzed that it is because of the too strict version of blis in your requirements.

blis is intentionally pinned to an older version because blis 0.9.x has known issues leading to segmentation faults in some kernels. I am a bit surprised however that pip does not install a binary wheel, since we do have an aarch64 wheel for Python 3.11:
