AttributeError: module 'exoplanet' has no attribute 'optimize' about exoplanet

[dfm]

You must not actually be using the updated exoplanet. Make sure that you pip uninstall exoplanet a few times and then update from GitHub. It has only been added within the past day or so...

Thanks. I re-installed from source and now get this:

  File "/home/michael/miniconda3/envs/hpk_env/lib/python3.7/site-packages/theano/gof/cmodule.py", line 2396, in compile_str
    (status, compile_stderr.replace('\n', '. ')))
Exception: ('The following error happened while compiling the node', GetClOp(TensorConstant{[-1.   0.3  0.2]}), '\n', 'Compilation failed (return status=1): In file included from /home/michael/.theano/compiledir_Linux-4.15--generic-x86_64-with-debian-buster-sid-x86_64-3.7.0-64/tmpk3a4zjpg/mod.cpp:7:0:. /home/michael/miniconda3/envs/hpk_env/lib/python3.7/site-packages/exoplanet-0.1.4.dev0-py3.7.egg/exoplanet/theano_ops/starry/include/theano_helpers.h:5:10: fatal error: Eigen/Core: No such file or directory.  #include <Eigen/Core>.           ^~~~~~~~~~~~. compilation terminated..

That suggests to me that you didn't recursively clone because Eigen is included in the starry submodule. Try running the following in your git checkout:

git submodule update --init --recursive

and then

pip uninstall exoplanet
python setup.py develop

or

pip uninstall exoplanet
python setup.py install

Thanks again. I did as suggested and receive new errors:
ERROR (theano.gof.opt): Optimization failure due to: constant_folding
AttributeError: ('The following error happened while compiling the node', MakeVector{dtype='int64'}(), '\n', "module 'numpy.core.multiarray' has no attribute '_get_ndarray_c_version'")

I googled these and they appear to be related to Theanos. I re-installed Theanos using pip and conda (both installed version 1.0.3). Theanos and numpy appear to work fine. Any idea? Sorry to bother again...

[hippke]

Ah! This last error is only present if numpy==1.16. It runs fine in numpy==1.15.
Probably worth checking compatibility with different theanos + numpy versions

[dfm]

This is a Theano problem (or maybe conda, depending on how you interpret it), not an exoplanet problem. Raise an issue there if you want, but that's not something that this repo will fix!

Note that Theano 1.0.4 is compatible with numpy 1.16 (as tested here: https://travis-ci.org/dfm/exoplanet).
