Just started to undertands this，how should I correct this error

As I can see from the last line, your path is in incorrect format. Either change it to r'C:\Users\GuoJiaHao\coco\annotations\instances_train2014.json' or 'C:/Users/GuoJiaHao/coco/annotations/instances_train2014.json'

Same issue here!!!

Code:

Load dataset

import shapes if config.NAME == 'shapes': dataset = shapes.ShapesDataset() dataset.load_shapes(500, config.IMAGE_SHAPE[0], config.IMAGE_SHAPE[1]) elif config.NAME == "coco": dataset = coco.CocoDataset() dataset.load_coco(COCO_DIR, "train")

Must call before using the dataset

dataset.prepare()

print("Image Count: {}".format(len(dataset.image_ids))) print("Class Count: {}".format(dataset.num_classes)) for i, info in enumerate(dataset.class_info): print("{:3}. {:50}".format(i, info['name']))

error:

Does anyone solve this issue? Can show me where is the code that cause this error?
