v23.08.00: adding unit test for end-to-end example (#669)

* adding unit test for multi-gpu example

* added test for notebook 03

* fixed formatting

* update

* update

* Update 01-ETL-with-NVTabular.ipynb

day of week is between 0 and 6; it must be scaled with a max value of 6 to produce correct values from the 0-1 range. If we do col+1 and scale with 7, then a section of the 0-2pi range (for Sine purposes) will not be represented.

* Update 01-ETL-with-NVTabular.ipynb

Reversed the previous edit for weekday scaling. It is correct that it should be scaled between 0-7, because day 0 (unused/nonapplicable after +1 added) overlaps with day 7 for Sine purposes. Monday should scale to 1/7, Sunday should scale to 7/7 to achieve even distribution of days along the sinus curve.

* reduce num_rows

* Update test_end_to_end_session_based.py

* Update 01-ETL-with-NVTabular.ipynb

* updated test script and notebook

* updated file

* removed nb3 test due to multi-gpu freezing issue

* revised notebooks, added back nb3 test

* fixed test file with black

* update test py

* update test py

* Use `python -m torch.distributed.run` instead of `torchrun`

The `torchrun` script installed in the system is a python script with
a shebang line starting with `#!/usr/bin/python3`

This picks up the wrong version of python when running in a virtualenv
like our tox test environment.

If instead this were `#!/usr/bin/env python3` it would work ok in a
tox environment to call `torchrun`.

However, until either the pytorch package is updated for this to
happen or we update our CI image for this to take place. Running the
python command directly is more reliable.

Full Changelog: v0.1.16...v23.02.00

v0.1.16

Highlights

1. Standardize the ModelOutput API:

• Remove ambiguous flags: ignore_masking and hf_format: #543
• Introduce the testing flag to differentiate between evaluation (=True) and inference (=False) modes: #543
• All prediction tasks return the same output
  #546
  • During training and evaluation: the output is a dictionary with three elements: {"loss":torch.tensor, "labels": torch.tensor, "predictions": torch.tensor}
  • During inference: The output is the tensor of predictions.

2. Extend the Trainer class to support all prediction tasks:

#564

• The trainer class is now accepting a T4Rec model defined with binary or regression tasks.
• Remove the HFWrapper class as the Trainer is now supporting the base T4Rec Model class.
• Set the default of the trainer's argument predict_top_k to 0 instead of 10.
  • Note that getting the top-k predictions is specific to NextItemPredictionTask and the user should explicitly set the parameter in the T4RecTrainingArguments object. If not specified, the method Trainer.predict() returns unsorted predictions for the whole item catalog.
• Support multi-task learning in the Trainer class: it accepts any T4Rec model defined with multiple tasks and/or multiple heads.

3. Fix the inference performance of the Transformer-based model trained with masked language modeling (MLM):

#551

• At inference, the input sequence is extended by a [MASK] embedding after the last non-padded position to take into account the target position. The hidden representation of the [MASK] position is used to get the next-item prediction scores.
• With this fix, the user doesn't need to add a dummy position to the input test data when calling Trainer.predict() or model(test_batch, training=False, testing=False)

4. Update Transformers4Rec to use the new merlin-dataloader package: #547

• The NVTabularDataLoader is renamed to MerlinDataLoader to use the loader from merlin-dataloader package.
• User can specify the argument data_loader_engine=‘merlin’ in the T4RecTrainingArguments object to use the merlin dataloader. It supports GPU and CPU environments. The alias nvtabular is also kept to ensure backward compatibility.
