Expected behaviour

Restarting the kernel should clear all variables and imports

Actual behaviour

After restarting the kernel, the variables remain in displayed in the “variables” tab of jupyter. Querying them from the interactive window’s command line results in the correct “name XX not defined”. However, imported modules are not reloaded

Steps to reproduce:

[NOTE: Self-contained, minimal reproducing code samples are extremely helpful and will expedite addressing your issue]

1. Create the following two scripts in the same folder:

test.py:

#%%
import test_fun as tf
#%%

a = 10
b = 20
# %%

c = tf.my_fun(a)
print(c)

test_fun.py:

import numpy as np

def my_fun(a):
    print('I have received ' + str(a))
    return 2*a

1. run test.py, notice the output is as expected. In passing, note that the variables are NOT present in the “variables” tab, but they appear if, having the tab open, some code is run through the Interactive Window command line.
2. make some modification to my_fun, for instance add another line like print('now I am printing an extra line').
3. Restart jupyter kernel by clicking on the “restart” button at the top of the window. Note that the old variables do not disappear from the “variables” tab, however querying them from the Interactive Window comman line results in an expected error as the variable is not in memory.
4. re-run test.py, notice the new line is not being printed, which means the imported module is not reloaded.

Variables not initially showing is tracked in https://github.com/microsoft/vscode-jupyter/issues/6993. Not clearing on restart is a bug, but I’ll add that to #6993 since I should fix both of those issues at the same time.

Sounds like this issue has been fixed–please file a new issue if this is not working for you.
