ImportError: could not import ellc

[famc2]

Hello,

phoebe.version
'2.3.59'

I follow this example:
http://phoebe-project.org/docs/2.3/examples/inverse_paper_examples

after this lines:
b.add_compute('ellc', compute='fastcompute')
b.set_value_all('ld_mode', 'lookup')
b.run_compute(compute='fastcompute')

I got error:
ImportError: could not import ellc

no result after googling

thank you!

All of the alternate backends are soft-dependencies - meaning that the other packages are not installed with phoebe automatically, but are required in order to use the backend. In this case, you're trying to run the ellc backend, so need to install ellc (which is available from pip).

I created a docs issue to update the notebook to make this more clear. Thanks for pointing this out!

OK, thank you
