annoying error messages when exiting script using pyhf

[tancredicarli]

I am using pyhf, version 0.6.2. I have a simple script that loads a workspace from a json file. When exiting I get some
strange error messages. Otherwise the program runs ok.
The messages are:

Exception ignored in: <function WeakMethod.__new__.<locals>._cb at 0x7fb987f11dc0>
Traceback (most recent call last):
  File "/usr/lib/python3.8/weakref.py", line 58, in _cb
  File "/usr/lib/python3.8/weakref.py", line 74, in __eq__
TypeError: isinstance() arg 2 must be a type or tuple of types
Exception ignored in: <function WeakMethod.__new__.<locals>._cb at 0x7fb987f11af0>
Traceback (most recent call last):

The script is as follows:

import pyhf
import json

filename = "atlas_jet2015_cifital_eta_1_Lambda_20_TeV"
# read json describing the workspace
with open(filename + ".txt") as serialized:
    spec = json.load(serialized)

# create workspace
workspace = pyhf.Workspace(spec)
print(json.dumps(workspace, indent=2))
model = workspace.model()

Can you provide python3 -m pip list? #1530 exists to try to fix this (see #1506). One current solution we've found is to downgrade Click -- e.g.

python3 -m pip install click~=7.0

should be a current stop-gap.

Yeah, closing this as it is duplicate of Issue #1506. If you have additional follow up or questions please use that Issue. As @kratsg already said, if you downgrade Click to <8.0 this will go away.
