line_profiler (%lprun) also broken from IPython upgrade

[Travis Scrimshaw]

I just installed the line profiler because I want to do %lprun, but this is broken in 7.4.beta2 (likely is beta0)

Volker and IPython upgrade people, please fix this (and %attach).

This was a known bug in line_profiler that is fixed with the 2.0 release.  Try upgrading to line_profiler==2.0 and let us know if there's still a problem.

Yes, upgrading fixed it. Thank you!

Best,

For anyone else who is interested, here is what I did to get this to work on OS X:

  sage -i openssl   # since pip complains about no ssl module in the Python build
  sage -f python2

Then

  sage -pip install line_profiler

installs a version of line_profiler, specific to OS X, which is broken as far as I can tell. At least it didn't work for me; if I tried %lprun at the Sage command line, it would respond like this:

  sage: %lprun?
  Object `%lprun` not found.
  sage: %lprun
  ERROR:root:Line magic function `%lprun` not found.

So I went to https://pypi.python.org/pypi/line_profiler/, downloaded the source code as a tarball, and did

  sage -pip install /path/to/tarball

Now it works.
