Could not find source code file when running in Jupyter lab 3.3.2

Problem

Still getting this error when running %lprun -f take_sqr take_sqr([1,2,3])

Are you sure you are running this program from the same directory
that you ran the profiler from?
Continuing without the function's contents.

But it's ok when running in iPython.

What is your line_profiler version ? You didn't include it in your report.

Seems to work for me:

(pyenv3.9.9) joncrall@toothbrush:~$ jupyter --version
Selected Jupyter core packages...
IPython          : 8.1.1
ipykernel        : 6.6.1
ipywidgets       : 7.7.0
jupyter_client   : 7.1.0
jupyter_core     : 4.9.1
jupyter_server   : not installed
jupyterlab       : not installed
nbclient         : 0.5.9
nbconvert        : 6.4.0

notebook         : 6.4.10
qtconsole        : 5.2.2
traitlets        : 5.1.1

This is with line_profiler 3.5.0

I then upgraded my jupyter packages and got the same correct result:

IPython          : 8.1.1
ipykernel        : 6.10.0
ipywidgets       : 7.7.0

jupyterlab       : 3.3.2
nbclient         : 0.5.13
nbconvert        : 6.4.5
nbformat         : 5.2.0
notebook         : 6.4.10
qtconsole        : 5.2.2
traitlets        : 5.1.1

Maybe try updating your versions? Although if this is an error because of IPython 7.x instead of 8.x we probably should fix it. (can't test that atm).

@Erotemic I confused that I got error running in jupyter lab and why should it upgrade IPython at 8.x? It's ok at IPython at 7.x for me.
