I have installed Jupyter notebook on a fresh install of debian for pi. I had it working perfectly on a previous install. I do not understand why it is not working on this install. Kernal will not start.

Is anyone able to shine some light on my situation?
change the ownership of the ~/.local/share/jupyter directory from root to pi using below cmd:
sudo chown -R pi:pi ~/.local/share/jupyter
Please Run this command if your kernel does not start or shows any issue it worked for me
"pip3 install --force-reinstall --upgrade jupyter"

After reinstalling the watson-cloud-developer as an administrator. I solve the problem. It seems that if we do not run the pip install command as an administrator, then the package cannot be installed correctly.

Docker-compose is written by python. It seems that you miss some python packages. You can refer to the following page of how to fix the python lib issue.
Matplotlib issue on OS X ("ImportError: cannot import name _thread")
Alternatively, you can try to install docker-compose as a container, the docker container contains appropriate environment for docker-compose.

I get this error when trying to run pyLint in LiClipse and using the option redirect messages to console. I ran the line on a command prompt without any errors. So the issue is with LiClipse no redirecting output properly. Any ideas ?
/usr/local/bin/pylint --rcfile=/Users/amansehgal/.rcfile --include-ids=y /Users/amansehgal/Documents/cis519/hw3_skeleton/boostedDT.py
This usually means that the console env is different from the LiClipse env.
To fix it, print the environment variables from inside LiClipse and from the shell.
You can do that by creating a python script such as:
for key, val in sorted(os.environ.items()):
print('%s:\n %s' % (key, '\n '.join(sorted(val.split(os.pathsep)))))
And then comparing the values you have in either case.
The most common issue would be in the PATH, PYTHONPATH, DYLD_LIBRARY_PATH (on mac) or LD_LIBRARY_PATH (on linux) env variables.
You can also try to start LiClipse from the same shell where you started your command so that it inherits the env variables you have from the shell.
I have google-cloud-storage pip installed into a lib directory and vendored in. It's running just fine locally during development of my python appengine app. However, when trying to run unit tests via nose and testbed I'm getting "The 'google-cloud-core' distribution was not found and is required by the application". Here is the stack:

Any thoughts?
I had the same issue with google-cloud-translate, I was forced to also install the package "globally", i.e. pip install google-cloud-translate.
After struggling a lot with this same issue I found out that the error was because the vendor pip lib wasn't in the PYTHONPATH before calling the nosetests.
Try adding the vendor lib to the PYTHONPATH and then run the tests.
export PYTHONPATH="$(HOME)/Projects/myproject/pip_lib:$$PYTHONPATH"; \
nosetests .
Dead kernel
The kernel has died, and the automatic restart has failed. It is possible the kernel cannot be restarted.
If you are not able to restart the kernel, you will still be able to save the notebook, but running code will no longer work until the notebook is reopened.
the above message is shown in notebook dashboard after i start python3.

We accidentally made a release of the ipykernel package which doesn't work on Python 3.5 on Windows. Once we realised this, we made a new release (version 4.3.1) to fix it.
You can upgrade by running:
pip install --upgrade ipykernel
If you had installed ipykernel using conda, the command would be:
conda update ipykernel
