Error when importing FileStorageObserver #884

Open k47h4 opened 2 years ago

k47h4 commented 2 years ago

I tried to re-run some code with the newest version of sacred that used to work with a sacred version from late 2019 and now get the following error. The problem already seems to occur when trying to import the FileStorageObserver. What would be the best fix for this issue?

I am using python version 3.6 on macOS Mojave 10.14.6.

Traceback (most recent call last): File "/Users/k47h4/anaconda3/envs/topdown_plasticity/lib/python3.6/site-packages/importlib_metadata-4.12.0-py3.6.egg/importlib_metadata/_compat.py", line 9, in from typing import Protocol ImportError: cannot import name 'Protocol'

During handling of the above exception, another exception occurred:

Traceback (most recent call last): File "run_code.py", line 5, in from sacred.observers import FileStorageObserver File "/Users/k47h4/anaconda3/envs/topdown_plasticity/lib/python3.6/site-packages/sacred/init.py", line 11, in from sacred.experiment import Experiment File "/Users/k47h4/anaconda3/envs/topdown_plasticity/lib/python3.6/site-packages/sacred/experiment.py", line 12, in from sacred.arg_parser import format_usage, get_config_updates File "/Users/k47h4/anaconda3/envs/topdown_plasticity/lib/python3.6/site-packages/sacred/arg_parser.py", line 14, in from sacred.serializer import restore File "/Users/k47h4/anaconda3/envs/topdown_plasticity/lib/python3.6/site-packages/sacred/serializer.py", line 1, in import jsonpickle File "/Users/k47h4/anaconda3/envs/topdown_plasticity/lib/python3.6/site-packages/jsonpickle-2.2.0-py3.6.egg/jsonpickle/init.py", line 81, in from .version import version # noqa: F401 File "/Users/k47h4/anaconda3/envs/topdown_plasticity/lib/python3.6/site-packages/jsonpickle-2.2.0-py3.6.egg/jsonpickle/version.py", line 5, in import importlib_metadata as metadata File "/Users/k47h4/anaconda3/envs/topdown_plasticity/lib/python3.6/site-packages/importlib_metadata-4.12.0-py3.6.egg/importlib_metadata/init.py", line 17, in from . import _adapters, _meta File "/Users/k47h4/anaconda3/envs/topdown_plasticity/lib/python3.6/site-packages/importlib_metadata-4.12.0-py3.6.egg/importlib_metadata/_meta.py", line 1, in from ._compat import Protocol File "/Users/k47h4/anaconda3/envs/topdown_plasticity/lib/python3.6/site-packages/importlib_metadata-4.12.0-py3.6.egg/importlib_metadata/_compat.py", line 12, in from typing_extensions import Protocol # type: ignore File "/Users/k47h4/anaconda3/envs/topdown_plasticity/lib/python3.6/site-packages/typing_extensions-4.3.0-py3.6.egg/typing_extensions.py", line 160, in class _FinalForm(typing._SpecialForm, _root=True): AttributeError: module 'typing' has no attribute '_SpecialForm'

The entire code can be found in this repository: https://github.com/k47h4/interneuron_circuits_plasticity Here is a code snippet from run_code.py:

from sacred.observers import FileStorageObserver

def run_in_thread(values):
    from Spiking_model import ex
    ex.observers.append(FileStorageObserver.create('Spiking_model'))
    ex.run('run_network')

values1 = np.array([0])
n_threads = len(values1)   
pool = multiprocessing.Pool(n_threads)
pool.map(run_in_thread, values1)

Thank you!

Hmm, it works for me (on Python 3.9). Does the same error occur when you just import jsonpickle?
