Add `jpeg_quality` parameter to `log_image` #2418

emilk · 2023-06-13T17:31:23Z

What

You can now do log_image("image", image, jpeg_quality=75) to compress your logged images so they take up less space on disk and in RAM.

I also updated the UI so you can actually tell whether or not a tensor was compressed.

This makes a many of our example data lot smaller. For instance, tracking_hf_opencv goes from 753 MB to 101MB.

OpenCV isn't the nicest dependency to have. For example, sometime one must use opencv-python-headless when it interferes with some UI toolkits, etc. Could we consider alternative package, e.g. Pillow?

emilk · 2023-06-13T18:13:03Z

Good idea - pillow we can probably depend on directly too; it is a pretty light dependency. Let's see if it supports jpeg compression…

EDIT: it did, and it works great!

nikolausWest · 2023-06-13T20:22:24Z

Pillow is supposed to be pretty slow. Did you test speed at all? simplejpeg looks like it might be a better fit.

Unfortunately, they dont back their bold (and indeed tempting) claims with proper binaries for Apple silicon. I tried to install the package, it installed from source, and failed :(

Edit: it looks like next release will fix this: https://gitlab.com/jfolz/simplejpeg/-/issues/7

Yes, this costs the user a bit of CPU at log-time. We could alleviate this by throwing the jpeg encoding in a background thread and wait for that thread on shutdown, but I don't want to do such a risky change right now. I've warned the user about the CPU cost in the docstring.

.github/workflows/reusable_build_and_test_wheels.yml needs fixing. I share @jleibs's perplexity around that part btw (line 242):

      - name: Install wheel dependencies
        if: needs.set-config.outputs.RUN_TESTS == 'true'
        # First we install the dependencies manually so we can use `--no-index` when installing the wheel.
        # This needs to be a separate step for some reason or the following step fails
        # TODO(jleibs): pull these deps from pyproject.toml
        # TODO(jleibs): understand why deps can't be installed in the same step as the wheel
        shell: bash
        run: |
          pip install deprecated numpy>=1.23 pyarrow==10.0.1 pytest==7.1.2

      - name: Install built wheel
        if: needs.set-config.outputs.RUN_TESTS == 'true'
        # Now install the wheel using a specific version and --no-index to guarantee we get the version from
        # the pre-dist folder. Note we don't use --force-reinstall here because --no-index means it wouldn't
        # find the dependencies to reinstall them.
        shell: bash
        run: |
          pip uninstall rerun-sdk
          pip install rerun-sdk==${{ steps.expected_version.outputs.EXPECTED_VERSION }} --no-index --find-links dist

Couldn't we just do that?

pip uninstall rerun-idk
pip install local/path/to/dist/rerun_xxx.whl

it might be nice to do this in rust instead in the future to make it more cross-platform and to introduce less python dependencies
