 This is a question, not really a defect.

 When I run the {{{py-scikit-image @0.12.3_1}}} tests I get a few fails
 from {{{dask}}} because {{{toolz}}} isn't installed. Here's one:
 {{{

 }}}


 Should {{{dask}}} (or {{{scikit-image}}}) have {{{toolz}}} as a
 dependency?

 At https://github.com/dask/dask/blob/master/setup.py#L13 I see that dask
 lists
 {{{
 extras_require = {
   'array': ['numpy', 'toolz >= 0.7.2'],
   'bag': ['cloudpickle >= 0.2.1', 'toolz >= 0.7.2', 'partd >= 0.3.7'],
   'dataframe': ['numpy', 'pandas >= 0.18.0', 'toolz >= 0.7.2',
                 'partd >= 0.3.7', 'cloudpickle >= 0.2.1'],
   'distributed': ['distributed >= 1.15', 's3fs >= 0.0.8'],
   'imperative': ['toolz >= 0.7.2'],
 }
 }}}
 and at https://github.com/conda-forge/dask-
 feedstock/blob/master/recipe/meta.yaml (written by the dask devs) I see
 this:
 {{{
 requirements:
   build:
     - python
     - setuptools

   run:
     - python
     - bokeh
     - cloudpickle >=0.2.1
     - numpy
     - pandas >=0.18.0
     - partd >=0.3.6
     - toolz >=0.7.2
 }}}
