[https://nvbugs/5520490][fix] Fix intermittent test failures by avoiding external web data pulls #7879
Conversation
Signed-off-by: Chang Liu (Enterprise Products) <[email protected]>
📝 WalkthroughWalkthroughTests for image/video token counting were updated to use local test assets instead of remote URLs. A local test_data_root was added, image/video loaders are used to open files, and the URL-based download helper was removed. Loops now iterate over local file paths and load PIL images/frames to read sizes. Changes

17-22: Prefer Path composition + global naming; define VIDEO_NUM_FRAMES constant.Improves readability and follows naming guidelines.

121-126: Avoid variable shadowing for clarity.Rename loop variable/path vs loaded object (e.g., image_path → pil_image).
214-221: Ensure video num_frames is passed to default_multimodal_input_loader.Keep encoder and predictor in sync (use VIDEO_NUM_FRAMES).
Proposed change (adjust arg name per verification):
inputs = default_multimodal_input_loader( tokenizer=tokenizer, model_dir=encoder_model_dir, model_type=model_type, modality="video", prompts=prompts, media=media, video_data_format="pt", video_num_frames=VIDEO_NUM_FRAMES, )
1-5: Drop unused imports to satisfy linters and the “no web pulls” goal.io, requests, and PIL.Image aren’t used after this change.
104-105: Comment nit: these are local paths, not URLs.Update comments to “All image paths” / “All video paths”.
Also applies to: 211-212
17-22: Harden offline execution in CI.Set these in test jobs to guarantee no network pulls:
- HF_HUB_OFFLINE=1
- TRANSFORMERS_OFFLINE=1
- CURL_NO_PROXY="*"

**/*.py: Python code must target Python 3.8+.
Indent Python code with 4 spaces; do not use tabs.
Maintain module namespace when importing; prefer 'from package.subpackage import foo' then 'foo.SomeClass()' instead of importing the class directly.
Python filenames should be snake_case (e.g., some_file.py).
Python classes use PascalCase names.
Functions and methods use snake_case names.
Local variables use snake_case; prefix 'k' for variables that start with a number (e.g., k_99th_percentile).
Global variables use upper SNAKE_CASE prefixed with 'G' (e.g., G_MY_GLOBAL).
Constants use upper SNAKE_CASE (e.g., MY_CONSTANT).
Avoid shadowing variables from an outer scope.
Initialize all externally visible members of a class in the constructor.
Prefer docstrings for interfaces that may be used outside a file; comments for in-function or file-local interfaces.
Use Google-style docstrings for classes and functions (Sphinx-parsable).
Document attributes and variables inline so they render under the class/function docstring.
Avoid reflection when a simpler, explicit approach suffices (e.g., avoid dict(**locals()) patterns).
In try/except, catch the most specific exceptions possible.
For duck-typing try/except, keep the try body minimal and use else for the main logic.

🔇 Additional comments (2)
tests/unittest/_torch/multimodal/test_find_num_image_tokens.py (2)
15-15: LGTM: use of local loaders avoids network.
228-233: Incorrect — frame-counts are consistent; no change required.default_multimodal_input_loader defines num_frames: int = 8 (tensorrt_llm/inputs/utils.py) and the test calls it without overriding, so encoder inputs use 8 frames; the test's local load_video(...) also uses num_frames=8. No action needed.
Likely an incorrect or invalid review comment.
