Question: I have to build an online application that shows a table with content being synchronized. That means, if the content of a table cell is being changed, every user has to receive the new content without reloading the site. A time delay of a couple of seconds means no problem.

The site is running as PHP content management system. There will be not more than 10 users at same time.

How would you do that? Using JS server-sent events? Interval of AJAX requests?

Answer: 
Just go to "Runtime" in the option menu then click on "Reset all runtimes..".

It helps me to restart kernel as in jupyter notebook happen when i'm trying to run this:

```
tf.executing_eagerly()

```
I used to use this command:

```
condacolab KERNEL RESTART \
print("Restarting of kernel...") \
get_ipython().kernel.do_shutdown(True)

```
