Installing edited code with pyproject.toml

[HuangJiameng]

When I try to install dpgen with edited source code using the command pip install ., the following ERROR occurs.

  ERROR: Command errored out with exit status 1:
   command: /usr/bin/python3 /usr/lib/python3/dist-packages/pip install --ignore-installed --no-user --prefix /tmp/pip-build-env-34etvn_j/overlay --no-warn-script-location --no-binary :none: --only-binary :none: -i http://mirrors.cloud.aliyuncs.com/pypi/simple/ --trusted-host mirrors.cloud.aliyuncs.com -- oldest-supported-numpy 'setuptools>=43.0.0' 'Cython>=0.29.23'
...
  ERROR: Could not install packages due to an EnvironmentError: [Errno 28] No space left on 

When I try another machine, another error occurs.

        File "/tmp/pip-standalone-pip-rsgk656_/__env_pip__.zip/pip/_vendor/urllib3/response.py", line 440, in _error_catcher
          raise ReadTimeoutError(self._pool, None, "Read timed out.")
      pip._vendor.urllib3.exceptions.ReadTimeoutError: HTTPSConnectionPool(host='files.pythonhosted.org', port=443): Read timed out.

I am not sure if I am installing it in the right way, so I search for https://stackoverflow.com/questions/62983756/what-is-pyproject-toml-file-for
And use pip install -e . to install with setup.py, which has the following contents:

import setuptools

if __name__ == "__main__":
    setuptools.setup()

However, it doesn't work.
I just want to ensure I have done it right, and if so, I will check my machine then.

Consider upgrading your pip.

After upgrading pip, problem still exist... pip._vendor.urllib3.exceptions.ReadTimeoutError: HTTPSConnectionPool(host='files.pythonhosted.org', port=443): Read timed out.

This looks like a network issue.
