My questions are: 1. where are the write / print statements that display *Successfully downloaded, extracting ...*
I would expect these to be in the tensorflow package. Find out where that is installed, then grep the source for "Successfully".
It is not uncommon for programmes to set their logging threshlds to emit "INFO" level logs if the output is a terminal, and possibly only "WARNING" or higher otherwise, so as to provide progress reporting to a person but less noise in a batch environment. So you may just be seeing info messages reporting progress. And it is likely that tere will be some mechanism to tune how noisy that it.
2. I don't see any such files in /tmp/data on my system, why?
These are probably temporary scratch files. The module will be fetching data files into the "/tmp/data" directory (which you have specified) and unpacking and importing their data. Once that is done the file is presumably discarded.
If you cd into that directory in another terminal and run "ls" commands regularly _during_ the import phase, you should see the filesappear and disappear as they are fetched, processed and discarded.
