Spyder: Spyder Does Not Launch After Updating Anaconda Packages

[staqiuddin]

Problem Description

I have Anaconda Python Distribution. After executing the conda update conda and conda update --all commands, Spyder no longer launches. Among the updated packages is spyder-kernels (updated to v1.0.1).

What steps reproduce the problem?

1. Execute conda update conda from Anaconda Prompt.
2. Execute conda update --all from Anaconda Prompt.
3. Launch Spyder.

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

Spyder should launch.

Needed this fix on Win7-64, conda=4.6.2, python=3.7.2. Reverted spyder-kernels from 1.0.1 to 0.3.0. Spyder now launches without error
