tmp_dir has to be set manually in `synthetic_data_experiment.py`

[nanls]

Is there a way for the script to find tmp_dir automatically ?

synthetic_data_experiment.py is currently using an arbitrary tmp dir that have to be set manually.

Attempt 1 : Using gettempdir() function from \tempfile\ python module

In parallel run, it does not work on cluster because slave nodes (on which qsub jobs are running) have not the same tmp dir than master node.

Attempt 2 : Try to access to tmp dir of master node from slave nodes
