My Situation
When I'm using the sage.all module just on the normal python shell, sage.all throws an error on running methods like solve or assume:
>>> import sage.all as sg;a=sg.var('a');sg.assume(a==0);
Traceback (most recent call last):

RuntimeError: ECL says: THROW: The catch MACSYMA-QUIT is undefined.
Running assume or solve on the sage shell (and preprocessor) works like it is supposed to do.
My Question
What can I do to get sage.all to work correctly on python?
Thanks - if anything's unclear concerning my question, please comment.
I would just use the Sage copy of the IPython shell.
$ sage -ipython

I am working with IDS camera and they have a python module called pyueye. I installed it using pip, but it seems like the dll are missing:

During handling of the above exception, another exception occurred:

I noticed someone else had the same issue in windows.
Does anyone else have the same issue using pyeue?
I had same issue but then I downloaded IDS Software Suite from https://en.ids-imaging.com/
Installed it and everything worked. Give it a try.
It will also let you configure their camera from IDS Camera Manager before you use it from Python.
I created my own docs for Read the Docs. See my repository
Some of my docs files are jupyter notebook so I used nbshpinx for it.
In my computer I installed all the dependencies and it works great when I use make html.
However, Read the docs throws the error:

Following this tutorial I created two yml files and the error changed to:
Error
Problem in your project's configuration. Invalid "conda.environment": environment not found
Solved it!
I followed this tutorial
I added in readthedocs.yml:
python:
version: 3
install:
- requirements: docs/requirements.txt
system_packages: true
And then in docs/requirements.txt:
ipykernel
nbsphinx
If questions you can always check the repository where I do it.
I have created virtualenv for python3 using:
virtualenv -p $(which python3) ENV
Then activate the source
source /Users/myusername/ENV/bin/activate
Install the apache-airflow:
pip install apache-airflow
then which airflow yields /Users/myusername/ENV/bin/airflow
But when I try to initdb using:
airflow initdb
I get below error:

(ENV) ---------------------------------------------------------
Seems like example scripts use python 2.7 and it can't recognize the function definition syntax.
Does apache-airflow package need to be fixed by the next release or I can do something to fix this?
I tried fixing this:
Use python2.7 instead of python3
then install airflow on default python 2.7 enabled on mac but this throws other errors like package "six" is not compatible.
You need to turn off the example DAGs to be loaded in config file to solve this problem.
Anyway, it seems weird that airflow uses 2.7 Python when you told that it is installed into Python 3 virtual environment.
I get this error after trying :
openmdao iprof x.py
or
openmdao iprof_totals x.py
on my terminal. Any idea why it could be? Do we have a simple sample code where the iprof works smoothly.

I looked into this and there is currently a bug when using 'openmdao iprof' and 'openmdao iprof_totals' on a version of OpenMDAO that was not installed from an OpenMDAO repository using 'pip install -e'. I put a story in our bug tracker to fix it.
I want to track the HTTP response codes returned by my nginx web-server, using logster.
1) I found and installed logster. I also pip-installed pygtail, which is required for logster.
https://github.com/etsy/logster
2) I found a python script that parses nginx access_log and placed it in the parsers subdir.
https://github.com/metabrainz/logster/blob/master/musicbrainz/logster/NginxStatus.py
...but when I run the logster command, I get a python exception:
Traceback (most recent call last):
File "/usr/local/bin/logster", line 5, in <module>

ImportError: No module named NginxStatus1
````
What am I doing wrong?
The exception error was rather misleading: the file was placed in the right place (the parsers subdir), but - as it turns out- logster must be re-setup after a new parser is added (this isn't documented, unfortunately). so just run:
sudo python setup.py install
in the logster directory and things should start working correctly.
