yolo5でtrain.pyを実行して学習する時にFileNotFoundError: [Errno 2] No such file or directory: ''エラーが出る

このサイトに従ってデータを用意し、googlecolabで学習をしていたのですが、train.pyを実行したところで

Traceback (most recent call last):
File "train.py", line 642, in <module>
main(opt)
File "train.py", line 538, in main
train(opt.hyp, opt, device, callbacks)
File "train.py", line 131, in train
model = Model(cfg, ch=3, nc=nc, anchors=hyp.get('anchors')).to(device) # create
File "/content/yolov5/models/yolo.py", line 92, in init
with open(cfg, encoding='ascii', errors='ignore') as f:
FileNotFoundError: [Errno 2] No such file or directory: '

とエラーが出てしまいます。
