运行megan时python错误求助

macas

运行MEGAN_EFP.py时，出现一个错误：UnicodeDecodeError: 'utf-8' codec can't decode byte 0x82 in position 203420: invalid start byte看网上有些解决方案，但好像都没用，不知道大神们有没有处理经验？

具体问题如下：

Creating VegType EF and LDF databases
ClassID: 1
./database/M3VTEF_database.mycase.d03.db

Database Initialization
Initialization Complete

Creating M3VTEF DB tables from: ./inputs/VegDB_Tables/

典型的编码问题，跟Megan不Megan关系应该不大。原则上传递文件自身的encoding就行了。

多谢回复，搞不懂在哪里进行修改

这个应该是megan里面的py 文件最好是在python2里面运行，你可以下个conda2试试
