not supporting PEP 517 builds - not specifying PEP 517 build requirements correctly - the build requirements are incompatible with your operating system or Python version - the build requirements are missing system dependencies (eg: compilers, libraries, headers). You can verify this by running pip wheel --no-cache-dir --use-pep517 "llvmlite (==0.34.0)". - Updating numpy (2.2.6 -> 2.3.1) PS C:\Users\Jonathan\documents\testing-sparse>
