symbol error while running "pyq -m notebook "

[alexzhang2010]

I am installed pyq 4.1.2 succesfully on redhat 2.7. When I run pyq from the shell, everything works fine.

(env_py36) [a393831@lrtp9101 ~]$ pyq
Python 3.6.3 |Anaconda custom (64-bit)| (default, Oct 13 2017, 12:05:00) 
[GCC 7.2.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import pyq
>>> print(pyq.__version__)
4.1.2
>>> 

But when I launched the notebook with "pyq -m notebook ", and tried to the above code from notebook. I received the following error (also see the attached screen shot)

In order to use pyq in a Jupyter notebook, you need to install pyq-kernel. See https://pypi.python.org/pypi/pyq-kernel.

pip install pyq-kernel
pyq -m pyq.kernel install

[abalkin]

Alternatively, if you don't need to interact with the kernel via kdb+ IPC, you can simply locate your main kernel.json file (e.g. using the jupyter kernelspec list command) end replace "python" with "pyq" in the "argv" list.

[alexzhang2010]

unfortunately, installing pyq-kernel does not help. This issue seems have something to do with anaconda 5.0. I downgraded it to anaconda 4.4 (with python 3.6.3, pyq 4.1.2) and it started working.

[abalkin]

How do you get Anaconda 5.0? I am looking at our recent Travis build https://travis-ci.org/KxSystems/pyq/jobs/305481268 and we seem to pick up conda-4.3.30.

[sashkab]

@abalkin anaconda distribution is 5.0.1, but conda package is... different. Different versions of anaconda.

@alexzhang2010 when you were using anaconda 5 based virtualenv, after you installed the pyq-kernel, did you change kernel from Python 3.6 to PyQ 3 kernel? Error message you were getting means, that most likely Python 3.6 kernel was used.

To help you troubleshoot -- please provide outputs of:

jupyter kernelspec list

And attach the .ipynb file with the notebook which failed to work.

[alexzhang2010]

https://www.anaconda.com/download/

The latest build is 5.0.1 released on 10/25

[alexzhang2010]

When I was using anaconda 4.4, I don’t have to install pyq-kernel. I just used python 3.6 kernel and import pyq works fine.

After I upgraded to anaconda 5.0.1, I got the same symbol error both with PyQ 3 kernel and with Python 3 kernel.

[sashkab]

@alexzhang2010 error you're getting is expected and is not a problem. In order to use IPython Notebooks with PyQ, you need to install ipython-kernel as suggested above by @abalkin, and use PyQ kernel for your notebook. While there you will have access to %q single line magic and %%q multiline magic.

[alexzhang2010]

With anaconda 5.0.1, I installed pyq-kernel and used the pyq3 kernel, I ran into the same error.

Why it works with anaconda 4.4 even without installing pyq-kernel?
