0004 ==========
0005
0006 Unfortunately attempting::
0007
0008    from opticks.ana.debug import MyPdb
0009
0010 Gives "Name error cannot import", so have to duplicate the
0011 below piece of code wherever wish to plant breakpoints for
0012 consumption by Pdb.
0013
0014 For a useful interactive stack dump presentation
0015 at "set_trace" breakpoints or errors use ip::
0016
0017     ip(){
0018         local py=${1:-dummy.py};
0019         ipython --pdb -i -- $(which $py) ${@:2}
0020     }
0021
0022 For example::
0023
0024    ip tboolean.py --tagoffset 0 --tag 1 --cat tboolean-box --pfx tboolean-box --src torch --show
