Classification_Machine Learning and Deep Learning based LULC in LiDO3

Some error occured during data processing in LiDO3.

Important: Be sure to use python3 xx.py and pip3 install --user packages in processing.

LiDO3 codes

$ module add python/3.7.7

$ pip3 install --user tifffile 

$ module add gdal/3.6.1-gcc122

$ python3 RandomForest.py

Errors

1. ImportError: No module named tifffile

Solution:

python程序中使用 import XXX 时，python解析器会在当前目录、已安装和第三方模块中搜索 xxx，如果都搜索不到就会报错。使用sys.path.append()方法可以临时添加搜索路径，方便更简洁的import其他包和模块。这种方法导入的路径会在python程序退出后失效。此时，可以通过增加path的方法来解决1:

import sys
sys.path.append('./venv/lib/python3.6/site-packages')
sys.path.append('./venv/lib64/python3.6/site-packages')
sys.path.append('/home/smyumeng/.local/lib/python3.6/site-packages')
sys.path.append('/cluster/sfw/gdal/3.6.1-gcc122/lib/python3.7/site-packages')

2. SyntaxError: Non-ASCII character ‘\xc2’ in file

YOU WILL LIKELY GET THIS ERROR if you import a PYTHON 3 file into the PYTHON 2 interpreter2. (This question should not be closed - ‘\xc2’ is a very particular sort of problem - and very different to that raised by the supposed duplicate question. The answer should be made clear here).

Solution:

Python3 RandomForest.py instead of python RandomForest.py
