Problem with training Scaled-YOLOv4 Pytorch on custom dataset tutorial

I am trying to train Scaled-YOLOv4 on custom dataset according to the tutorial provided by Roboflow. I followed all the code on the Google Colab exactly. I used the code below for training:

# train scaled-YOLOv4 on custom data for 100 epochs
# time its performance
%cd /content/ScaledYOLOv4/
!python train.py --weights 'weights/yolov4-csp.conv.142' --cfg 'models/yolov4-csp.yaml' --img 416 --batch 16 --epochs 100 --data {dataset.location}/data.yaml --cache --name yolov4-csp-results  

However, when trying to run the command for training, I got the following error:
