NameError: name 'null' is not defined

Workaround

Use jupyter-notebook

No module named tabulate

from tabulate import tabulate

is showing following error:

No module named tabulate

Workaround
Use following command to install tabulate

sudo pip install tabulate

name 'os' is not defined

In Experiment 2
name 'os' is not defined

Following line is throwing error:
pcaErr = [metricData['PCA']['Err'][0],np.asarray(metricData['PCA']['Err'][1:]).mean()]

Below is the error trace:

urllib3 related error "InsecurePlatformWarning: A true SSLContext object is not available"

This error is not directly related to the code. However it can be seen while trying to update jupyter. Below is the error message:

IOError: [Errno 2] No such file or directory: '/usr/local/lib/python2.7/dist-packages/appdirs-1.4.0.dist-info/METADATA'
/usr/local/lib/python2.7/dist-packages/pip/_vendor/requests/packages/urllib3/util/ssl_.py:122: InsecurePlatformWarning: A true SSLContext object is not available. This prevents urllib3 from configuring SSL appropriately and may cause certain SSL connections to fail. You can upgrade to a newer version of Python to solve this. For more information, see https://urllib3.readthedocs.io/en/latest/security.html#insecureplatformwarning.
  InsecurePlatformWarning

Workaround:

It seems that urllib3 is creating some blockage while jupyter is trying to update itself. Removing urllib3 doesn't help in this case. Below is the workaround:

pip install appdirs --upgrade

IOError: [Errno 2] No such file or directory: '../Data/Data.p'

In experiment1.ipynb file inside Exp2
IOError: [Errno 2] No such file or directory: '../Data/Data.p'
