Basic example:
python caption_cog.py --image_dir /mnt/mydata/kyrie/ --prompt 'Describe this image in detail, including the subject matter and medium of the artwork.'
Use probabilistic sampling by using any of top_k, top_p, or temp:
python caption_cog.py --image_dir \"c:/users/chadley/my documents/pictures\" --prompt \"What is this?\" --top_p 0.9
Use beam search and probabilistic sampling:
python caption_cog.py --image_dir \"c:/users/chadley/my documents/pictures\" --prompt \"Write a description.\" --max_new_tokens 75 --num_beams 4 --temp 0.9 --top_k 3 --top_p 0.9 --repetition_penalty 1.0 --no_repeat_ngram_size 0 --min_new_tokens 5
Force "cat" and "dog" and disallow the word "depicts":
python caption_cog.py --image_dir /mnt/lcl/nvme/mldata/test --num_beams 3 --force_words "cat,dog" --bad_words "depicts"
Use a lot of beams and try to control the length with length_penalty:
python caption_cog.py --image_dir /mnt/lcl/nvme/mldata/test --num_beams 8 --length_penalty 0.8 --prompt "Write a single sentence description."
Notes:
1. Setting top_k, top_p, or temp enables probabilistic sampling (aka "do_sample"), otherwise greedy sampling is used.
a. num_beams 1 and do_sample false uses "greedy decoding"
b. num_beams 1 and do_sample true uses "multinomial sampling"
c. num_beams > 1 and do_sample true uses "beam-search multinomial sampling"
d. num_beams > 1 and do_sample false uses "beam-search decoding"
2. Max_length and max_new_tokens are mutually exclusive. If max_new_tokens is set, max_length is ignored. Default is max_length 2048 if nothing set.
Using Max may abruptly end caption, consider modifying prompt or use length_penalty instead.
