Hi, This question may be stupid, I am just a beginner at python. I created a new environment successfully installed the requirements.txt. Also the downloader by "pip install semeval_8_2022_ia_downloader".
When I used "python -m semeval_8_2022_ia_downloader.cli --links_file=input.csv --dump_dir=output_dir", it said "FileNotFoundError: [Errno 2] No such file or directory: 'input.csv'".
Would you please tell me what should I do? Thank you!

The error above indicates that the file input.csv does not exist. The idea is to change the command and specific a file of URLs that should be downloaded. For example, you can download semeval-2022_task8_train-data_batch.csv from the dataset on Zenodo and then update the Python command to be

python -m semeval_8_2022_ia_downloader.cli --links_file=semeval-2022_task8_train-data_batch.csv --dump_dir=output_dir"

This will read the urls from semeval-2022_task8_train-data_batch.csv and put the output in a new directory (folder) called output_dir.

The full Zenodo data set is at
