spyder does not launch in conda environment #11680

Open smaffei opened 4 years ago

smaffei commented 4 years ago

Actual Behavior

I created a new environment (called it 'dedalus' as the use of that model was the purpose of the environment, but I don't think it's important) with conda, with python 3.7.6 in it (among other things). Everything else in the environment seem to be working fine. I would like to use spyder to code, so I open Anaconda-Navigator and try to launch spyder (version 4.0.1, already tried to update it). Instead of launching, an "Application Launch error" window opens with the following Traceback:

Traceback (most recent call last): File "/opt/anaconda3/envs/dedalus/bin/spyder", line 11, in sys.exit(main()) File "/opt/anaconda3/envs/dedalus/lib/python3.7/site-packages/spyder/app/start.py", line 201, in main from spyder.app import mainwindow File "/opt/anaconda3/envs/dedalus/lib/python3.7/site-packages/spyder/app/mainwindow.py", line 167, in from spyder.utils.environ import WinUserEnvDialog File "/opt/anaconda3/envs/dedalus/lib/python3.7/site-packages/spyder/utils/environ.py", line 19, in from spyder.plugins.variableexplorer.widgets.collectionseditor import ( File "/opt/anaconda3/envs/dedalus/lib/python3.7/site-packages/spyder/plugins/variableexplorer/widgets/collectionseditor.py", line 57, in from spyder.plugins.variableexplorer.widgets.collectionsdelegate import ( File "/opt/anaconda3/envs/dedalus/lib/python3.7/site-packages/spyder/plugins/variableexplorer/widgets/collectionsdelegate.py", line 31, in from spyder.plugins.variableexplorer.widgets.objectexplorer.attribute_model \ File "/opt/anaconda3/envs/dedalus/lib/python3.7/site-packages/spyder/plugins/variableexplorer/widgets/objectexplorer/init.py", line 19, in from .attribute_model import DEFAULT_ATTR_COLS, DEFAULT_ATTR_DETAILS File "/opt/anaconda3/envs/dedalus/lib/python3.7/site-packages/spyder/plugins/variableexplorer/widgets/objectexplorer/attribute_model.py", line 29, in import numpy as np File "/opt/anaconda3/envs/dedalus/lib/python3.7/site-packages/numpy/init.py", line 142, in from . import core File "/opt/anaconda3/envs/dedalus/lib/python3.7/site-packages/numpy/core/init.py", line 107, in from . import _internal File "/opt/anaconda3/envs/dedalus/lib/python3.7/site-packages/numpy/core/_internal.py", line 20, in IS_PYPY = platform.python_implementation() == 'PyPy' File "/opt/anaconda3/envs/dedalus/lib/python3.7/platform.py", line 1264, in python_implementation return _sys_version()[0] File "/opt/anaconda3/envs/dedalus/lib/python3.7/platform.py", line 1225, in _sys_version repr(sys_version)) ValueError: failed to parse CPython sys.version: '3.7.6 (default, Jan 8 2020, 13:42:34) \n[Clang 4.0.1 (tags/RELEASE_401/final)]'

Expected Behavior

I would expect spyder to launch and work. It does on the base environment (with Python 3.7.4 and spyder 3.3.6) or on a python 2 environment (python 2.7.17 and spyder 4.0.1).

Steps to Reproduce

  1. Open Anaconda-Navigator
  2. Activate the dedalus environment
  3. click on the spyder launcher

Alternatively

  1. open the terminal

  2. activate the dedalus conda environment

  3. launch spyder via

    spyder or spyder -- reset

  4. observe the spyder icon jumping in the doc and receive the error message (either in Anaconda-Navigator or in the terminal)

Does switching to a python package from defaults fix this issue?

smaffei commented 4 years ago

I am sorry, I don't understant what it is that you are suggesting. Are you suggesting to switch to the base environment? If that is what you mean, by switching to the base environment, I seem to be able to start spyder. I also have a python 2 environment from which I can start spyder

jjhelmus commented 4 years ago

I noticed that the python package in the dedalus environment is coming from the conda-forge channel. It is possible that this is causing an issue. Installing a version from defaults may resolve this. This can be done using conda install -c default -n dedalus python.
