请问训练时报这个错因为什么呢？

路径问题，你检查一下image_path看看最后面是不是多了个/，源代码image_name = image_path + image_file有点问题，这样写就可以解决了image_name = os.path.join(image_path, image_file)

您好，修改代码image_name = os.path.join(image_path, image_file)后依然报错

数据集定义：CONVERSATION_DATA = {

'data_1': {
    'images': '/mnt/f/GOT-OCR2.0/GOT-OCR-2.0-master/Data-for-LaTeX_OCR/fullhand/images',
    'annotations': '/mnt/f/GOT-OCR2.0/GOT-OCR-2.0-master/Data-for-LaTeX_OCR/fullhand/data.json',
},

}
请问这是因为什么呢
