KeyError: 'scm_version' during installation

<!-- Feel free to change the order of sections if appropriate. --> **Describe the bug** I had to explicitly set `GPUSTAT_VERSION` to bypass the execution of the `read_version` [function](https://github.com/wookayin/gpustat/blob/7a3b9644229681a752b560c6d4889929b9ea39d5/setup.py#L37). I am wondering whether this is the intended behaviour and whether maybe a pyproject.toml + conforming to more recent build tooling may help. **Screenshots or Program Output** ```bash matbun@mylaptop$ docker run -it --rm python:3.12 bash root@f528d76dbdd3:/# pip install gpustat==1.1.1 Collecting gpustat==1.1.1 Downloading gpustat-1.1.1.tar.gz (98 kB) Installing build dependencies ... done Getting requirements to build wheel ... error error: subprocess-exited-with-error × Getting requirements to build wheel did not run successfully. │ exit code: 1 ╰─> [26 lines of output] Traceback (most recent call last): File "/usr/local/lib/python3.12/site-packages/pip/_vendor/pyproject_hooks/_in_process/_in_process.py", line 389, in <module> main() File "/usr/local/lib/python3.12/site-packages/pip/_vendor/pyproject_hooks/_in_process/_in_process.py", line 373, in main json_out["return_val"] = hook(**hook_input["kwargs"]) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/usr/local/lib/python3.12/site-packages/pip/_vendor/pyproject_hooks/_in_process/_in_process.py", line 143, in get_requires_for_build_wheel return hook(config_settings) ^^^^^^^^^^^^^^^^^^^^^ File "/tmp/pip-build-env-g44nh1xn/overlay/lib/python3.12/site-packages/setuptools/build_meta.py", line 331, in get_requires_for_build_wheel return self._get_build_requires(config_settings, requirements=[]) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/tmp/pip-build-env-g44nh1xn/overlay/lib/python3.12/site-packages/setuptools/build_meta.py", line 301, in _get_build_requires self.run_setup() File "/tmp/pip-build-env-g44nh1xn/overlay/lib/python3.12/site-packages/setuptools/build_meta.py", line 512, in run_setup super().run_setup(setup_script=setup_script) File "/tmp/pip-build-env-g44nh1xn/overlay/lib/python3.12/site-packages/setuptools/build_meta.py", line 317, in run_setup exec(code, locals()) File "<string>", line 37, in <module> File "<string>", line 26, in read_version File "/tmp/pip-build-env-g44nh1xn/overlay/lib/python3.12/site-packages/setuptools_scm/_integration/dump_version.py", line 77, in dump_version write_version_to_path( File "/tmp/pip-build-env-g44nh1xn/overlay/lib/python3.12/site-packages/setuptools_scm/_integration/dump_version.py", line 111, in write_version_to_path content = final_template.format(version=version, version_tuple=version_tuple) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ KeyError: 'scm_version' [end of output] note: This error originates from a subprocess, and is likely not a problem with pip.
