Unable to bind `scipy.sparse.csr_matrix.log1p`

[npow]

Hi, I encountered a strange issue trying to bind scipy.sparse.csr_matrix.log1p. It's saying ModuleNotFoundError: No module named 'scipy.sparse.csr_matrix', but it does exist?

from pipelinex import HatchDict
import yaml
from pprint import pprint  # pretty-print for clearer look

import scipy.sparse
assert scipy.sparse.csr_matrix.log1p

params_yaml = """
fn:
  =: scipy.sparse.csr_matrix.log1p
"""
parameters = yaml.safe_load(params_yaml)
fn = HatchDict(parameters).get("fn")
print(fn)
