benchmark installation error, ModuleNotFoundError: No module named 'main'

Question

为什么会出现这个错误？我不能再安装基准了。我需要导入包含在基准测试中的 'get_data'。怎么了？

pip 安装基准测试

benchmark 不兼容 python 版本 >= 3.

你需要python 2.

在虚拟环境中 python 3

~/workspace/so via  v3.8.5 via C python3 
❯ pip install benchmark
Collecting benchmark

与 python 2 :

~/workspace/so via  v2.7.18 :: Anaconda, Inc. via C python2 
❯ pip install benchmark           
DEPRECATION: Python 2.7 will reach the end of its life on January 1st, 2020. Please upgrade your Python as Python 2.7 won't be maintained after that date. A future version of pip will drop support for Python 2.7. More details about Python 2 support in pip, can be found at https://pip.pypa.io/en/latest/development/release-process/#python-2-support
