Here is something so embedded in stan, I can’t begin to debug. I have ep-stan code running just fine, but when I attempt to parallelize it by dishing out worker code to worker nodes, I get a strange error
File “/usr/local/lib64/python2.7/site-packages/pystan/model.py”, line 666, in sampling
fit = self.fit_class(data)
File “stanfit4SimpleAdAttribEP_sg_f3b10500566451c7863bb6c6a0d1260c_7800964287842110052.pyx”, line 463, in stanfit4SimpleAdAttribEP_sg_f3b10500566451c7863bb6c6a0d1260c_7800964287842110052.StanFit4Model.init
TypeError: init() takes exactly 2 positional arguments (1 given)
This .pyx file seems to be a temporary file, so I can’t open it to exam, and I don’t know at which stage it get generated, therefore, no clue why there is this signature mismatch.
Can any stan interior expert shed some light?
