I'm running a jupyter notebook with PyQ kernel and able to run both python and q code. BUT: whenever a cell produces an error (like calling a nonexisting_function()), no more cells are executed until I restart the kernel. In contrast, with Python kernel, I can run other (or same) cells after an error, too, which I consider a normal behavior.
I'm using miniconda3 with virtual environment (mypyq) on 64bit ubuntu.
(mypyq) user@workstation:~$ conda --version
conda 4.5.11
(mypyq) user@workstation:~$ conda list

(mypyq) user@workstation:~$ jupyter notebook --debug

Running 6*7 in the notebook:
[D 09:37:54.476 NotebookApp] activity on ...: status
[D 09:37:54.476 NotebookApp] activity on ...: execute_input
[D 09:37:54.477 NotebookApp] activity on ...: execute_result
[D 09:37:54.479 NotebookApp] activity on ...: status
Cell output is 42, all ok so far.
Now running nonexisting() in the notebook:
[D 09:38:38.266 NotebookApp] activity on ...: status
[D 09:38:38.267 NotebookApp] activity on ...: execute_input
[D 09:38:38.315 NotebookApp] activity on ...: error
[D 09:38:38.317 NotebookApp] activity on ...: status
Notebook cell output:
------------------------------------
NameError Traceback (most recent call last)
<ipython-input-2-124a31d9d771> in <module>
----> 1 nonexisting()
NameError: name 'nonexisting' is not defined
Running 6*7 cell again:
[D 09:39:29.799 NotebookApp] activity on ...: status
[D 09:39:29.799 NotebookApp] activity on ...: status
I'm missing at least ...: execute_result in the console. And there no output in the notebook as well, until I restart the kernel.
This does not happen with Python kernel, only with PyQ kernel. Running PyQ in the console is ok, too:

After running an errorneous cell, when I shutdown jupyter notebook server with Ctrl-C, it reports timing out and killing the kernel.

This bug has been fixed in the pyq-kernel 1.0.1, which was recently released. Thank you for your report.
