Hello,
I am working on a physical constants module, but for whatever reason I
can't get it to correctly import the units module.
I import the units class using "from units import units", but I get:

AttributeError: 'module' object has no attribute 'all'
Error importing ipy_profile_sage - perhaps you should run %upgrade?
WARNING: Loading of ipy_profile_sage failed."
Is it a problem that physical_constants is imported in all.py along
with the units module? Because when I run the file using %run, there
is no error. I don't see what other way there is to do it though.
Thanks!
