Spyder 5.2.2 incompatible to Anaconda 3

[jeng87]

ISSUE
New version of Spyder 5.2.2 is not compatible to be run under Anaconda 3 ClearMapStable.yml environment, instead Spyder 3 would be forced to run automatically. However, many Spyder 3 dependencies do not support to ClearMap2.

ANSWER
Use Anaconda 3 ClearMap.yml instead to create an environment with flexible package dependencies and then run ClearMap2 scripts in Spyder 3. Because ClearMapStable.yml is the version with frozen package dependencies which can create restriction of changing certain dependency's version. Thus, try to use ClearMap.yml first.

You can also skip (comment) spyder in the ClearMap.yml file and then
pip install 'spyder<5'
