帮我写一个批量将yolopose转换成单个json文件的cvat导出的cocokeypoints的脚本

好的，以下是一个简单的Python脚本，可以将yolopose转换成单个json文件的cvat导出的cocokeypoints：

import json
import os

input_dir = "/path/to/input/files/"
output_dir = "/path/to/output/files/"

for filename in os.listdir(input_dir):
    if filename.endswith(".json"):
        with open(os.path.join(input_dir, filename), "r") as f:
            data = json.load(f)
            new_data = []
            for frame in data["shapes"]:
                keypoints = []
                for point in frame["points"]:
                    keypoints.append(point[0])
                    keypoints.append(point[1])
                    keypoints.append(2) # set score to 2 (high confidence)
                new_data.append({"keypoints": keypoints})
            output_filename = os.path.join(output_dir, filename[:-5] + "_converted.json")
            with open(output_filename, "w") as outfile:
                json.dump(new_data, outfile)

请注意，您必须将“/path/to/input/files/”和“/path/to/output/files/”替换为实际的输入和输出目录，然后运行脚本即可。
