can not install in setuptools>v57 environment #9
Description
Abstract
I found that xfeat could not be installed in an environment where the version of setuptools was v58 or higher. This issue may be due to the fact that 'ml_metrics' which xfeat depends on, ml_metrics uses 'use_2to3' option.
https://github.com/zhouyonglong/ml_metrics/blob/master/Python/setup.py#L14
However, use_2to3 option is already not supported in setuptools v58 or higher.
https://setuptools.pypa.io/en/latest/history.html#v58-0-0
Therefore, the installation will fail with the following error.
$ pip install xfeat
Collecting xfeat
Downloading xfeat-0.1.1-py3-none-any.whl (39 kB)
Collecting ml-metrics
Downloading ml_metrics-0.1.4.tar.gz (5.0 kB)

note: This error originates from a subprocess, and is likely not a problem with pip.

note: This is an issue with the package mentioned above, not pip.
hint: See above for details.Note that if you have installed xfeat in the past in an environment with setuptools<v58, the installation will succeed with cached wheels.
Workaround
Downgrade setuptools < v58 and install xfeat.
$ pip install -U "setuptools<58"
$ pip install xfeatEnvironment
