Object has no attribute '__code__'

[oiao]

Hi there, I noticed that sample_space does not seem to work with class instances, because they do not have a __code__ attribute:

import exmol
class A:
    pass
exmol.sample_space('C', A(), batched=True)

AttributeError: 'A' object has no attribute '__code__'

Is there any way around this other than forcing the call to a separate function?

Not exactly sure how your class is supposed to work, but here are a few examples:

Make class on each call:

import exmol
class A:
    def __call__(self, seqs):
      # do something with seqs
      return ys
obj = A()
exmol.sample_space('C', obj, batched=True)

Make new object each time

def wrapper(seqs):
  my_a = A()
  return my_a(seqs)
exmol.sample_space('C', wrapper, batched=True)

Did this fix your issue @oiao ?

Sorry for the late reply Andrew.
The second example works, but the first one - providing a class object directly to sample_space - would still fail with the same AttributeError described above. It's not a major issue since one can always wrap the call into another function. I was just wondering if this could be addressed somehow.

Ah, I think I understand now what's going on. Have a PR on #118 that should fix this. It was also broken for function partials

Perfect, thanks a lot!
