同事的本子上用pip install scikit-learn 安装时报错说:
sklearn\\datasets\\tests\\data\\openml\\1119\\api-v1-json-data-list-data_name-adult-census-limit-2-data_version-1.json.gz'
再执行一次pip install scikit-learn居然不报错了说安装成功了！但是使用到sklearn时报错:

以前我自己没到过这个奇怪的问题，搜了国内网上一些解决办法无非是卸载scikit-learn然后重装，甚至是重装scipy，试过了都没用。
网上找了一下sklearn有关网站，从https://zenodo.org/record/3596890这里发现以前的版本，比如0.20.1、0.22.1，确实内部包含有api-v1-json-data-list-data_name-adult-census-limit-2-data_version-1.json.gz这个文件，高版本就没有了，于是先把高版本的numpy之类的相关的包先卸载掉，再用
pip install scikit-learn==0.20.1
安装一下，结果使用sklearn时还是报上面的错误，郁闷了，这肯定是版本对不上的问题，但是到底是哪里版本对不上呢？想想可能是python本身有问题？不确定，再去墙外搜，果然搜到了一篇文章说是安装了32位的python有这个问题，于是卸载掉现有python安装64位的python，问题解决，猜测可能的原因是python在高版本中没有顾及32位版本的兼容性吧。
