Can't access statsmodels.stats.api

posted May 25, 2020

Hi, I'm trying to use statsmodels.stats.api.acorr_ljungbox but I can't seem to access it. Below is the error:

AttributeError                            Traceback (most recent call last)  
<ipython-input-47-69fcdb2ad26a> in <module>()  
      1 import statsmodels  
----> 2 statsmodels.stats.api.acorr_ljungbox

/build/src/qexec_repo/qexec/algo/safety.py in __getattribute__(self, attr)
    163             # Calls the unbound method of the super class on `module`.  
    164             result = super(ModuleWrapper, type(self)).__getattribute__(  
--> 165                 module, attr,  
    166             )  
    167 

AttributeError: module 'statsmodels.stats' has no attribute 'api'

It does appear on the Algorithm IDE whitelist though: https://www.quantopian.com/docs/whitelists/ide-whitelist#algo-ide-whitelist

I'm trying to access it from research, which as I understand, has access to a superset of IDE modules. Any help would be appreciated!

Any of the following approaches will work to import statsmodels and ultimately access acorr_ljungbox.

import statsmodels.stats  
# it can then be accessed `statsmodels.stats.api.acorr_ljungbox`

import statsmodels.stats as sm  
# it can then be accessed `sm.api.acorr_ljungbox`

import statsmodels.stats.api  
# it can then be accessed `statsmodels.stats.api.acorr_ljungbox`

import statsmodels.stats.api as sm_api  
# it can then be accessed `sm_api.acorr_ljungbox`

Happy coding.
