Can we use subfolder = os.path.join(self.mode)?
It makes the intentions of this line much clearer to the reader.

subfolder is just a string and not a filepath.

os.path.join returns an object of type str. If I understand this part correctly, the subfolder variable contains the path to sub directory for tensorboard data?

no subfolder is just the name of the reduction. each reduction will be its own subfolder in the tensorboard directory.

We should rename the name of this map. Maybe something more explicit like self.tb_writer_to_dir_map ?

When do we accept an empty string collection name?
Should we use the DEFAULT collection key?

I extended this part, which is needed for Tensorboard to group visualizations by Debugger collections. To keep it consistent with previous code, the collection name will be empty per default.

What is the value of scalar if tb_writer = None?

Per default Debugger writes reductions like normal tensors into debug-output folder and users can retrieve the data via the smdebug API. I extended this part, so that reductions are also written in Tensorboard format (in case user provided a Tensorboard configuration)

Can we manage reduction_name values with Enums?

Description of changes:
Extended smdebug's reductions to check for nan- and inf-values and to compute quantiles for PT tensors. Tensors are now also written out in Tensorboard format such that users can display all reductions for a specific tensor within the same visualization and visualizations will be grouped by Debugger collections.
Here is an example visualization:
