人在环机器学习系统搭建与实践

1. 构建获取人工标签的接口

在构建接口以获取人工标签时，会根据用户输入的标签进行不同操作。以下是相关代码及操作逻辑：

# 代码部分
if 满足某种条件:
    ind-=1  # go back
elif label == "d":                    
    print(detailed_instructions) # print detailed instructions
elif label == "s":
    break  # save and exit
else:
    if not label == "1":
        label = "0" # treat everything other than 1 as 0
    data[ind][2] = label # add label to our data
    if data[ind][3] is None or data[ind][3] == "":
        data[ind][3] = default_sampling_strategy # default if none given
    ind+=1        
else:
    #last one - give annotator a chance to go back
    print(last_instruction)
    label = str(input("\n\n> ")) 
    if label == "2":
        ind-=1
    else:
        ind+=1
