Exception 'missing key "sweep_by_type"'

[thorstenhater]

Describe the bug
Downloading files with electro-physiological model from the cell-types DB, I repeatedly
run into the error

[...]
multiprocessing.pool.RemoteTraceback:
"""
Traceback (most recent call last):
  File "/usr/local/Cellar/python/3.7.7/Frameworks/Python.framework/Versions/3.7/lib/python3.7/multiprocessing/pool.py", line 121, in worker

I followed the steps mentioned here

AllenSDK

To Reproduce

Install AllenSDK via pip

pip3 install --user allensdk

Download cell models

from allensdk.api.queries.biophysical_api import BiophysicalApi

ids = [497232312, 491766131]
bp = BiophysicalApi()
bp.cache_stimulus = True
for id in ids:
    bp.cache_data(id, working_directory=f'model-{id}')

Run models

cd model-491766131
python3 -m allensdk.model.biophysical.runner manifest.json

Expected behavior
Model runs without error.

Actual Behavior
The exception above gets thrown.

Environment (please complete the following information):

• OS & version: MacOs 10.15.4 (Catalina)
• Python version 3.7
• AllenSDK version 1.7.1

Additional context
NEURON installed via MacOs installer, modfiles compiled successfully

I also have the same problem.

It should be noted that to reproduce the error we had to modify the following line:

https://github.com/AllenInstitute/AllenSDK/blob/master/allensdk/model/biophysical/utils.py#L324

as follows:

         morph_extension = morph_basename.decode('ascii').split('.')[-1]

Environment

• Arch Linux
• Python 3.8.2
• AllenSDK 1.7.1
• Neuron 7.6.8 (compiled from git tag 7.6)

I created a fresh virtual environment, and ran pip install numpy; pip install allensdk (numpy must be installed because one of the dependencies uses it in their setup.py.)

I tried again with the latest 2.0 release:

• Arch Linux
• Python 3.8.2
• AllenSDK 2.0.1 (installed in a clean virtual env with pip)
• Neuron 7.8.0.127 (installed via pip)

The ascii issue has been fixed, however KeyError: 'sweeps_by_type' is still occurring.

I am having same issue while running models as described by @thorstenhater. Any help to fix / workaround this issue will be great!

Edit : Ok, I see that the input json files (e.g. manifest.json) has "runs": [ key which needs to have section with sweeps_by_type. Not sure why the provided input files are missing this configuration.
