When I open SageMath Console, it will show such a paragraph:
/opt/sagemath-9.1/local/lib/python3.7/site-packages/psutil/_pscygwin.py:311: DeprecationWarning: invalid escape sequence \d
search = re.compile('cpu\d')/opt/sagemath-9.1/local/lib/python3.7/site-packages/psutil/_pscygwin.py:876: DeprecationWarning: invalid escape sequence \d
def uids(self, _uids_re=re.compile(b'Uid:\t(\d+)')):/opt/sagemath-9.1/local/lib/python3.7/site-packages/psutil/_pscygwin.py:887: DeprecationWarning: invalid escape sequence \d
def gids(self, _gids_re=re.compile(b'Gid:\t(\d+)')):
And the operating system I use is Windows 10 1909, the SageMath I use is version 9.1. Is this a bug?
