What do you get from jupyter kernelspec list
?
Hello, this is what I got, thanks! jupyter kernelspec list Available kernels: julia-0.3 /Users/haihan/Library/Jupyter/kernels/julia-0.3 python2 /Users/haihan/Library/Jupyter/kernels/python2
Have a look in /Users/haihan/Library/Jupyter/kernels/python2/kernel.json
. The first value in argv
should be the path to a Python interpreter. What path has it got?
Hello, thanks for your replies.
the first argv
is "/Library/Frameworks/Python.framework/Versions/2.7/Resources/Python.app/Contents/MacOS/Python",
thanks a lot!
I had the same issue resolved it by running python2 -m ipykernel install --user
@ronteo I had the same issue and this fixed it. Thanks!
@chisoo You are very welcome. Glad it worked!
@ronteo this fixed my jupyter too. Thanks a lot!!
I have the same issue.
After I check the argv
path in my kernel.json
what should I do?
Running jupyter kernelspec list
gives me /home/aulon/.local/share/jupyter/kernels/python2
,
but the argv
value is /usr/bin/python2
.
I tried replacing argv
with /home/aulon/.local/share/jupyter/kernels/python2
and still the same error.
I feel like I am missing a database.
[W 06:54:04.215 NotebookApp] The signatures database cannot be opened; maybe it is corrupted or encrypted. You may need to rerun your notebooks to ensure that they are trusted to run Javascript. The old signatures database has been renamed to /home/aulon/.local/share/jupyter/nbsignatures.db.bak and a new one has been created.

@takluyver please, what do you suggest?
Thanks
For Anaconnda users issue can be fixed by changing python.exe to pythonw.exe

@saxenaPAWAN worked like a charm! Thank you!
I used
conda install jupyter
to install without a problem. Then I open the jupyter notebook, kernel error appears. I also usepython -m IPython kernelspec install-self
to reinstall kernel, but it cannot solve the problem
