Problem Description

I have NO issue when installing Spyder with default Python (version =3.7.4) in a new environment (conda create --name coursera_Kaggle python spyder). However, when I specified the Python version to be 3.6, and installed Spyder (conda create --name coursera_Kaggle python=3.6 spyder), Spyder cannot launch. I tried the latest version 4.0.1 and version 3.3.6, and neither of them launches.

Spyder was installed via Anaconda on Windows 10.

I first tried the “reset” shortcut associated with the new environment (such a script shortcut was created after the new environment was created and Spyder was installed), but it still doesn’t solve the issue. Instead of working in the new environment, it clears/resets the setting the base environment, i.e. after running the reset script, my Spyder in the base environment was reset to the default settings.

I searched online and tried all solutions I can find, but none of them works.

What steps reproduce the problem?

1. conda create --name coursera_Kaggle python=3.6 spyder
2. conda activate coursera_Kaggle
3. spyder

for version 3.3.6, the first command line is

conda create --name coursera_Kaggle python=3.6 spyder=3.3.6

What is the expected output? What do you see instead?

It doesn’t launch.
