 An image usually accounts for 2000 input tokens. For example, an image of size 512x512 is represented by 2800 tokens. Thus, `max-input-tokens` must be larger than the number of tokens associated to the image. Otherwise the image may be truncated. We set `BASE_IMAGE_TOKENS=2048` as the default image token number. This is the minimum value of `max-input-tokens`. You can override the environment variable `BASE_IMAGE_TOKENS` to change this value. The warmup will generate graphs with input length from `BASE_IMAGE_TOKENS` to `max-input-tokens`. For LLava-next 7B, the value of `max-batch-prefill-tokens` is 16384, which is calcualted as follows: `prefill_batch_size` = `max-batch-prefill-tokens` / `max-input-tokens`.
