ERROR: Path for Bokeh server application does not exist: /home/superusr/Desktop/colaboratory_python/show

I have a python script file in this path ‘/home/superusr/Desktop/colaboratory_python/plot.py’ which successfully plots the required plot on notebook, but to make it interactive I want to use bokeh server
I tried running the script with following commands .(tried both)

bokeh serve -- show plot.py
python3 -m bokeh serve -- show plot.py

but both the commands give the following error

ERROR: Path for Bokeh server application does not exist: /home/superusr/Desktop/colaboratory_python/show

Please help me where I am doing wrong. A can I get guidelines for how to launch a bokeh server, how to use it

Thank you

Remove the -- from your command.
