Unable to run jupyter notebook due to kernel error #5019

Open nataliemur26 opened 4 years ago

nataliemur26 commented 4 years ago

I tried to run jupyter notebook --NotebookApp.iopub_data_rate_limit=10000000000 in order to load a plot, however, it ended up not allowing me to open jupyter notebook, after I tried to uninstall pymzq and the reinstall it...and now I am left with the error below:

Traceback (most recent call last): File "C:\Users\Natalie\Anaconda3\lib\site-packages\traitlets\traitlets.py", line 528, in get value = obj._trait_values[self.name] KeyError: 'loop'

During handling of the above exception, another exception occurred:

The following shows up for kernalspeclist:

Try jupyter kernelspec list

nataliemur26 commented 4 years ago

Using jupyter kernelspec list gives the following:
