请问您这个问题解决了吗？

I am getting the same error as well.

[sidb236]

After installing all the libraries in requirement.txt of yolov5 and deepsort, we run the command
python main.py --cam 0

and get the error as:

Traceback (most recent call last):
File "D:/Projects/yolov5-deepsort/DeepSORT_YOLOv5_Pytorch/main.py", line 259, in

Please help.

In the file parser.py in line 34,

if name == "main":
cfg = YamlParser(config_file="../configs/yolov3.yaml")
cfg.merge_from_file("../configs/deep_sort.yaml")

import ipdb; ipdb.set_trace()

We are creating a cfg object by passing yolov3.yaml in the configs directory. This file is absent in the configs directory. Moreover, we are using yolov5 here. I guess this could be the error here. Will passing the yolov5 yaml file correct this error?

[sidb236]

Still getting the same error. Please help.

Still getting the same error. Please help.

hi, i find a method to solve this. as stack-overflow, you can just change load() to safe_load() in ./ultils_ds/paser.py line23. OR !pip install pyyaml==5.4.1.
but other errors still occurs for some module not found, i think maybe requirements.txt need to be updated. i am try to find a Docker image which could run this repo or build one now.

Replace with this code
def merge_from_file(self, config_file): with open(config_file, 'r') as fo: self.update(yaml.load(fo.read(), Loader=yaml.FullLoader))

After modifying the parser, there is still error msg

请在后面加入这个，这是因为yaml文件的加载函数已经更新了。yaml.load(file,Loader=yaml.FullLoader)

replace yaml.load with yaml.safe_load
