FileNotFound Error in demo

[Haochen-Luo]

Hi, Krasser

When I run the demo script in colab I got the following error. Could you help me with this issue? I have installed all the packages required.
Thanks a lot.

!python generate.py \
--user-dir task \
--features obj \
--tokenizer moses \
--bpe subword_nmt \
--bpe-codes output/codes.txt \
--beam 5 \
--split test \
--path /content/drive/MyDrive/checkpoint24.pt \
--input demo/demo-ids.txt \
--output demo/demo-predictions.json

Namespace(no_console_output=False, output='demo/demo-predictions.json', split='test') ['--user-dir', 'task', '--features', 'obj', '--tokenizer', 'moses', '--bpe', 'subword_nmt', '--bpe-codes', 'output/codes.txt', '--beam', '5', '--path', '/content/drive/MyDrive/checkpoint24.pt', '--input', 'demo/demo-ids.txt']
