Environment configuration stepping pit during colab use

Problem description : Recently, with colab Run a model , Two packages can only be configured through conda install , There is also a non binary package ( need ！python setup.py install install ), When my environment is configured ,conda list I found all the bags in , but import XXX But remind me that this does not exist modle.

solve ： I have been troubled by this problem for nearly a day , I'm really sad , I lay on the ground pulling Chopin ……

I tried many methods on blog , Including what restart conda Kernel activation environment , Don't pretend miniconda And refit anaconda…………

The person in charge can tell you , None of the above mentioned works well

The final solution to my problem is these two lines of code ：

#  hold conda The package path of the package is added to the environment 
import sys
sys.path.append("/usr/local/lib/python3.6/site-packages")

The specific reason for this blog is very clear ：https://www.cnblogs.com/liulunyang/p/14291526.html

Essentially colab It is not supported anaconda or miniconda This kind of environmental management , however conda Is available .

I hope to help people who have the same problems as me .
