帮我改一下代码，如果是"error_msg":"pic not has face",帮我跳过这个文件的处理，import csv import os import json from IPython import display pic_folder_path = "./期末作业-面部数据/face_images/a4" output_list = [] no_result_list = [] for filename in os.listdir(pic_folder_path): if filename.endswith(".jpg"): pic_path = os.path.join(pic_folder_path, filename) result = None while not result or "result" not in result or "face_list" not in json.loads(result)["result"]: result = main(pic_path) # 调用主函数获取结果 result_dict = json.loads(result)["result"]["face_list"] if not result_dict: no_result_list.append(filename) for item in result_dict: output_list.append({ "filename": filename, "type": item["emotion"]["type"] }) # 输出未能识别结果的图片名称 print("无法识别结果的图片：", no_result_list) # 将结果保存为csv文件 with open("output.csv", "a", newline="") as f: writer = csv.DictWriter(f, fieldnames=["filename", "type"]) # writer.writeheader() writer.writerows(output_list)

可以在获取 result 后加上一行代码判断是否为"error_msg":"pic not has face"，如果是的话就跳过这个文件的处理，代码如下：

import csv
import os
import json
from IPython import display

pic_folder_path = "./期末作业-面部数据/face_images/a4"
output_list = []
no_result_list = []

for filename in os.listdir(pic_folder_path):
    if filename.endswith(".jpg"):
        pic_path = os.path.join(pic_folder_path, filename)
        result = None
        while not result or "result" not in result or "face_list" not in json.loads(result)["result"]:
            result = main(pic_path)  # 调用主函数获取结果
        result_dict = json.loads(result)["result"]
        if "error_msg" in result_dict and result_dict["error_msg"] == "pic not has face":
            continue
        result_dict = result_dict["face_list"]
        if not result_dict:
            no_result_list.append(filename)
        for item in result_dict:
            output_list.append({
                "filename": filename,
                "type": item["emotion"]["type"]
            })

# 输出未能识别结果的图片名称
print("无法识别结果的图片：", no_result_list)

# 将结果保存为csv文件
with open("output.csv", "a", newline="") as f:
    writer = csv.DictWriter(f, fieldnames=["filename", "type"])
    # writer.writeheader()
    writer.writerows(output_list)

这样，程序会在获取到"error_msg":"pic not has face"时直接跳过该文件的处理，继续处理下一个文件。
