Session cannot generate requests on displaying invalid code

[CGHolm]

Expected behaviour

Running these:

import numpy as np


N = 100
L = np.random.random((N, N))
A = np.identity(N) - 0.1* (np.identity - L)

A

Should print a python error due to this operation: (np.identity - L).

Actual behaviour

Ι get the following error:

Error: Session cannot generate requests

Steps to reproduce:

Run the above python code in three cells.

Thanks for the bug.

I can't seem to repro the issue. I get this:

My only guess is that your version of numpy or ipykernel is crashing the kernel with that code.

My versions are these:

What versions do you have?
