AttributeError: Can't pickle local object 'new_dist_class.<locals>.new_class'

[Seth Allen]

Hi there, 

I'm struggling to save models using the Hrl package, I'm generating the model as follows: m_rl = hddm.Hrl(data, dual=True, depends_on={'v':'dbs', 'pos_alpha':'dbs', 'alpha':'dbs'}) m_rl.sample(5000,burn=500, dbname='traces.db', db='pickle') m_rl.print_stats() 

and then I try to save using: m_rl.save('HRL_MODEL') 

however, I get the following error: 

Traceback (most recent call last): File "<stdin>", line 1, in <module> File "C:\Users\sallen\anaconda3\envs\HDDM3.6\lib\site-packages\kabuki\hierarchical.py", line 412, in save pickle.dump(self, open(fname, 'wb')) AttributeError: Can't pickle local object 'new_dist_class.<locals>.new_class' 

Greatly appreciate any help, 

Seth

Unfortunately, RL and RLDDM models can't be saved. As an alternative, I'd recommend saving the traces to a csv.
