I don't know if you have encountered my following problem: use pip to install pycaret:
pip install -i https://pypi.tuna.tsinghua.edu.cn/simple pycaret
The following error occurs:
(I use the anconda virtual environment)

Only part of the screenshot was taken, and there are still many errors below. . .
Then I went to the community, Baidu and other places to find a solution. Someone said that it would be good to install a visual studio c++ compiler. I installed it, but still reported an error. Then I thought the environment variables were not configured properly, so the configuration is as follows Environment variables:
The problem is still not resolved, here are a few high-quality articles during my period (not useful to me):

In the end my solution was to install directly with the conda command:
conda install pycaretReplace source, quick install:
Of course, if you haven’t changed the source before, you can refer to this article to change the source first, and then install: https://blog.csdn.net/chuihui4955/article/details/100757695?ops_request_misc=%257B%2522request%255Fid%2522%253A% 2522164419664716780271569275%2522%252C%2522scm%2522%253A%252220140713.130102334..%2522%257D&request_id=164419664716780271569275 &biz_id=0&utm_medium=distribute.pc_search_result.none-task-blog-2~all~sobaiduend~default-1-100757695.first_rank_v2_pc_rank_v29&utm_term=conda% E6%9B%B4%E6%8D%A2%E6%B8%85%E5%8D%8E%E6%BA%90&spm=1018.2226.3001.4187

A warning shows that you have changed the source. Then install:

list it
conda list
Hurry up and call it in jupyter: success! !
from pycaret.utils import version
version()
Pit: But this package will have a lot of errors when using python3.9.7
As for why I can't install pycaret with pip, I think it's because I didn't create a virtual environment, and then some packages are confused, that is, the version is incompatible? Then switching to conda installation is equivalent to creating an environment for me?
UPDATE ///2/8/2022:
Today I found out the real reason why I couldn't install pycaret before:
My virtual environment uses python 3.9.7. Using this version to pip install pycaret will report an error. I use conda to create a python=3.8 environment and install it without error.
Perfect solution:
#创建一个新的虚拟环境
conda create --name pycaret python=3.8
#激活
conda activate pycaret
#安装
pip install pycaret -i https://pypi.tuna.tsinghua.edu.cn/simple #换源安装
After the installation is complete, you can put the environment in jupyter, the command is as follows:
python -m ipykernel install --user --name pycaret --display-name "Python pycaret"
#如果报错：先 conda install ipykernel See this blog post for details: https://blog.csdn.net/qq_36441393/article/details/88229540
pycaret.datasets loading data error solution:
When I was using it, I reported a lot of mistakes because of the bad network, and finally got it resolved according to this article: https://blog.csdn.net/weixin_39861255/article/details/109983327
The error is reported because the github website cannot be accessed, or the network speed is slow.
Solution: Open Notepad in administrator mode and open 'C:\Windows\System32\drivers\etc\host'.
Add the following line at the end of the file and save it.

This article is used to record one night and one morning of invalid packaging debugging process, I hope it will be helpful to you.
