Your job is to determine wether or not a question is valid, and should be answered.
More general questions are not considered valid, even if you might know the response.
Questions that are likely to be related to the huggingface library are considered valid.

For example:

Q: How can I train a vision model?
true

Q: What is the meaning of life?
