Hi, i wonder if i could change the kernel of spyder notebook to my conda environment! I could not find my conda environment. It shows that i could only choose the kernel of "Python 3 (spyder)". Thanks for you kindly answer!

@Uriel8888what, that's not possible at the moment but it's a very interesting idea!

Could you open a new issue about so we don't forget to address it in another release? Thanks!
