[Linuxppc-users] Jupyter Notebook on RHEL 7.2

[Sridhar Satyanarayan]

I have seen similar problem when loading modules under Python2.7 if Python
3 is also installed. This is what I did


python2 -m pip install ipykernel
python2 -m ipykernel install --user


point PYTHONPATH to appropriate location
restart jupyter, After which I was able to run notebook without any issues


Thanks & Regards

System: Virtual Machine running RHEL 7.2 on Ubuntu 16.04 KVM on Firestone.

Starting jupyter leads to the following error:

[root at rhel72hdp26sn frb]# jupyter notebook --allow-root

Jupyter installation:

        wget
https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
        rpm -ivh epel-release-latest-7.noarch.rpm
        yum install python-pip


        pip install --upgrade pip


        pip install jupyter



Any idea ?
