1. 报错信息

ImportError: cannot import name 'AAA' from 'textattack.search_methods' 
(/home/666/anaconda3/envs/textattack37_env/lib/python3.7/site-packages/textattack/search_methods/__init__.py)

2. 出错简述

贴一段test1.py的模块导入

#建议使用！
import os
os.environ['HF_ENDPOINT'] = 'https://hf-mirror.com' 
#忽略警告!
import warnings
warnings.filterwarnings("ignore")
#问题出在这！
from textattack.constraints.grammaticality import PartOfSpeech
from textattack.constraints.pre_transformation import (RepeatModification, StopwordModification,)
from textattack.constraints.semantics.sentence_encoders.universal_sentence_encoder import UniversalSentenceEncoder
from textattack.goal_functions import UntargetedClassification
from textattack.search_methods import AAA
from textattack import Attack

from textattack.transformations import WordSwapMaskedLMSA

3. 解决方案

出现问题的原因：mytest与textattack是同级目录，mytest里的test1.py找不到外边的textattack模块，所以就用的虚拟环境的textattack！

解决方案1：

把test1.py拿出来，放到与textattack文件夹同级目录，就能正确找到AAA

解决方案2：

考虑不同文件夹之间模块调用，用sys.path.append('../textattack')

from textattack.constraints.grammaticality import PartOfSpeech
from textattack.constraints.pre_transformation import (RepeatModification, StopwordModification,)
from textattack.constraints.semantics.sentence_encoders.universal_sentence_encoder import UniversalSentenceEncoder
from textattack.goal_functions import UntargetedClassification
###########################
#from textattack.search_methods import AAA  #原
#### 改
import sys
sys.path.append('../textattack')
from search_methods import SimulatedAnnealnig  #search_methods下可能会有红色波浪线
###########################
from textattack import Attack
import textattack
from textattack.transformations import WordSwapMaskedLMSA

第二种方法试过了，需要改动的太多了😭
