Spyder: error occured while starting the kernel

[Markus Heller]

Hi,

this is with Spyder 3.3.6 and conda 4.7.10.

I installed conda and created a new environment, into which I installed the Spyder kernels (0.5.1, same as in base environment), as described here: https://github.com/spyder-ide/spyder/wiki/Working-with-packages-and-environments-in-Spyder.

  Spyder is able to connect to the kernel using the Default Python interpreter, but if I want to use the interpreter of the new environment, I get the following traceback in the ipython console:

Traceback (most recent call last):

This is most likely an issue with my computer config, since the approach described works fine on a colleague's machine, but I have no idea where to look.  File permissions should be identical on both machines (set by out IT department).  I'd be grateful for any hints ...

I had a similar problem that spyder was not working with the virtual environment. I just used installed spyder in that environment and problem gets resolved. This is the simplest way but you will need to install every time wherever you create a new environment.

But you can do it with the base version by changing the interpreter setting and path of the spyder. Hope this may help you.
