完美解决令人头疼的No module named 'copy_reg\r'

出现的原因：Windows和Linux下的文件编码不同，会在每行的末尾多出恶心的‘\r\n‘，解决方法，对字节码格式的每行‘\r\n‘替换为‘\n‘

1. 替换代码

import pickle

# 替换
with open(‘./pet.pickle‘,‘rb‘) as f:
    lines=f.readlines()
    lines=[str(x, encoding="utf-8") .replace(‘\r\n‘,‘\n‘) for x in lines]
    lines=[ bytes(x, encoding="utf8") for x in lines]

# 写入新的文件
with open(‘./washData/pet.pickle‘,‘wb‘) as nf:
    for line in lines:
        nf.write(line)

2. 测试

import pickle

with open(‘./washData/pet.pickle‘,‘rb‘) as f:
    p=pickle.load(f, encoding=‘latin1‘)
    print(p)
