Hello, can you please provide the steps to reproduce this problem?

jstaf commented 5 years ago

On Linux, you can reproduce this with the following (only place I've noticed it so far is in jupyter console):

To install:

go get -u github.com/gopherdata/gophernotes
mkdir -p ~/.local/share/jupyter/kernels/gophernotes
cp $GOPATH/src/github.com/gopherdata/gophernotes/kernel/* ~/.local/share/jupyter/kernels/gophernotes

To reproduce:

$ jupyter console --kernel=gophernotes

Hmmm, looks like you can "fix" the warning with --ZMQTerminalInteractiveShell.use_kernel_is_complete option:

$ jupyter console --kernel=gophernotes --ZMQTerminalInteractiveShell.use_kernel_is_complete=False

In [2]: fmt.Println("test") 
      :  
      :
