338684879  by Andre Araujo:

    Clean up summaries in DELF/G training script.

    - Previously, the call to tf.summary.record_if() was not working, which led to summaries being recorded at every step, leading to too large events files. This is fixed.
    - Previously, some summaries were computed at iteration k, while others at iteration k+1. Now, we standardize summary computations to always run after backpropagation (which means that summaries are reported for step k+1, referring to the batch k).
    - Added a new summary: number of global steps per second; useful to see how fast training is making progress.

    Also a few other small modifications are included:
    - Improved description of the train.py script.
    - Some small automatic reformattings.

326369548  by Andre Araujo:

--
326159826  by Andre Araujo:

    Changed the implementation of the cosine weights from Keras layer to tf.Variable to manually control for L2 normalization.

--
326139082  by Andre Araujo:

    Support local feature matching using ratio test.

    To allow for easily choosing which matching type to use, we rename a flag/argument and modify all related files to avoid breakages.

    Also include a small change when computing nearest neighbors for geometric matching, to parallelize computation, which saves a little bit of time during execution (argument "n_jobs=-1").

--
338731551  by Andre Araujo:

    Add image_size flag in DELF/G OSS training script.

--
338684879  by Andre Araujo:

    Clean up summaries in DELF/G training script.

    - Previously, the call to tf.summary.record_if() was not working, which led to summaries being recorded at every step, leading to too large events files. This is fixed.
    - Previously, some summaries were computed at iteration k, while others at iteration k+1. Now, we standardize summary computations to always run after backpropagation (which means that summaries are reported for step k+1, referring to the batch k).
    - Added a new summary: number of global steps per second; useful to see how fast training is making progress.

    Also a few other small modifications are included:
    - Improved description of the train.py script.
    - Some small automatic reformattings.

330022709  by Andre Araujo:

    Export joint local+global TF2 DELG model, and enable such joint extraction.

    Also, rename export_model.py -> export_local_model.py for better clarity.

    To check that the new exporting code is doing the right thing, I compared features extracted from the new exported model against those extracted from models exported with a single modality, using the same checkpoint. They are identical.

    Some other small changes:
    - small automatic reformating
    - small documentation improvements
