Unable to even load it once.
Minimum example to replicate the issue

!pip install -q ipyexperiments
import ipyexperiments as ipye
print(ipye.__version__)

[OUT:1]

0.1.17

[IN:2]

exp1 = ipye.IPyExperimentsPytorch()

Also tried after running the following, with no effect:

!pip install git+https://github.com/nicolargo/nvidia-ml-py3

Thank you for your report, @rahulraj80

It looks like colab is running an old ipython (5.5.0) which doesn't support the modern ipython events API:

You can upgrade it:

For posterity copying the full code from the above solution here:

!pip install -q --upgrade ipython
!pip install -q --upgrade ipykernel

# Restart with new IPython.
import os
import signal
os.kill(os.getpid(), signal.SIGTERM)

Run that cell, which will report a crash, then run your code normally. then everything works.

I updated the package requirements to require ipython>= 6.0.0, so it will be automatically updated when you install ipyexperiments. But it'll still require restarting the notebook for this to work.

To check which ipython you have run:

import IPython

IPython.version_info
IPython.__version__
