Install and Atmospheric Retrieval Issues

[Tusay]

I am a grad student, trying to get PandExo running on linux in order to model JWST atmospheric retrieval with usable output.

I have installed ExoCTK using the github clone and setup.

When I go to run the atmospheric retrieval demo, I get some errors.

First, when I go to import exoctk.atmospheric_retrievals.platon_wrapper I get the following: "pandeia not installed. Functionality limited. WARNING: The $EXOCTK_DATA environment variable is not set. Contamination overlap will not work. Please set the value of this variable to point to the location of the exoctk_data download folder. Users may retreive this folder by clicking the "ExoCTK Data Download" button on the ExoCTK website, or by using the exoctk.utils.download_exoctk_data() function. WARNING: LOCAL JWST PRD VERSION PRDOPSSOC-031 DOESN'T MATCH THE CURRENT ONLINE VERSION PRDOPSSOC-045-003 Please consider updating pysiaf, e.g. pip install --upgrade pysiaf or conda update pysiaf

RuntimeError Traceback (most recent call last) RuntimeError: module compiled against API version 0xf but this version of numpy is 0xd Batman library not installed. Install it by doing "pip install batman-package" to use exoctk.limb_darkening.spam.

RuntimeError Traceback (most recent call last) RuntimeError: module compiled against API version 0xf but this version of numpy is 0xd Could not import batman. Functionality may be limited.

RuntimeError Traceback (most recent call last) RuntimeError: module compiled against API version 0xf but this version of numpy is 0xd Could not import batman. Functionality may be limited."

I definitely have the pandeia data uncompressed and an environment variable set to its location. I also definitely set the $EXOCTK_DATA environment variable, so I don't know why it's complaining about those. I'm also unsure what's wrong with batman. I cannot import it without the same errors popping up, but I installed it independently and it says the requirements are already met. But when I run the cell again, the error warnings disappear.

Then, when I try to execute pw = PlatonWrapper() I get this error: "--------------------------------------------------------------------------- RuntimeError Traceback (most recent call last) /tmp/ipykernel_29345/3999841698.py in ----> 1 pw = PlatonWrapper() 2 pw.set_parameters(params)

RuntimeError: To avoid confusion, use CombinedRetriever instead"

All I'm trying to do is get a version of PandExo for JWST working where I can retrieve the data. The website provides a nice interface and a pretty output, but I need the data. If there's a way to just grab the data from the website instead of fighting with code please let me know. Otherwise, any help resolving the issues above would also be greatly appreciated.

Hi @Tusay,

I reccommend that, if the models are what you need, you grab them from "Forward Modeling" in the right of ExoCTK's online app: https://exoctk.stsci.edu/.

Let me know if this helps your particular use-case!

I appreciate the suggestion, but I really need the errors on the response with JWST's MIRI, so I am not sure the forward modeling will work for my case. I need the data from the PandExo --> JWST calculation.

Atmospheric retrieval tool was removed from the package so I'm closing this issue.
