[I 21:00:06.283 NotebookApp] KernelRestarter: restarting kernel (1/5)

[suvarchal]

repo is awaiting a major update with many changes to jupyter meanwhile, in about a week i will try to update it.

I managed to fix those tabs and spaces problem and the kernel compiles OK and I can load it in a notebook. However, trying the example
import java OK
print dir(java) Nothing appears on output

And I see the following exception in kernel:

[IPKernelApp] ERROR | Exception in message handler:
Traceback (most recent call last):

if len(self._child.before.splitlines())>1: out+='\n'.join(self._child.before.splitlines()[1:])+'\n'
TypeError: sequence item 0: expected str instance, bytes found

Is this exception related with the fact that I used python3.6 to install the kernel?

Do I need to use python2.7?

This is still an issue.
