Trying to use requests module in eventlet python2 hit below error.
>>> import eventlet
>>> eventlet.patcher.import_patched('requests')
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/usr/lib/python2.7/site-packages/eventlet/patcher.py", line 120, in import_patched

File "/usr/lib/python2.7/site-packages/requests/__init__.py", line 112, in <module>
from . import utils
ImportError: cannot import name utils
So how why this module can not be patched?
How could we know if one module can be patched?
It's a known issue, we don't have a solution yet. Sorry.
Workaround: eventlet.patcher.import_patched('requests.__init__')

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:

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 am trying to configure remote logging with Azure blob.
Airflow version: 1.10.2
Python: 3.6.5
Ubuntu: 18.04
Following are the step I did:
In $AIRFLOW_HOME/config/log_config.py, I have put REMOTE_BASE_LOG_FOLDER = 'wasb-airflow-logs' (This is a folder inside the container (container name: airflow-logs))
Empty init.py is in $AIRFLOW_HOME/config/
$AIRFLOW_HOME/config/ is added in $PYTHONPATH
Renamed DEFAULT_LOGGING_CONFIG to LOGGING CONFIG everywhere in $AIRFLOW_HOME/config/log_config.py
User defined in Airflow blob connection has read/write access to REMOTE_BASE_LOG_FOLDER
$AIRFLOW_HOME/airflow.cfg it has remote_logging = True
logging_config_class = log_config.LOGGING_CONFIG
remote_log_conn_id =
Following is the error:
Unable to load the config, contains a configuration error.

I am not sure which configuration I am missing. Has anyone faced the same issue?
You need to install the azure package.
pip install 'apache-airflow[azure_blob_storage,azure_data_lake,azure_cosmos,azure_container_instances]
As per updating.md
This now should be installed with
pip install apache-airflow[azure]
But this didn't work for me.
sudo chown 50000:0 dags logs plugins in my case.
I tried to run official docker-compose.yml with all these containers (which are dependent on these 3 volume forwards) or simply wrap airflow standalone into a single container for a debug purpose. Turned out volumes were created with root ownerships instead of airflows.
I had the same error however if I scrolled up higher I could see that there was another exception thrown before the ValueError. Which was a PermissionError.
PermissionError: [Errno 13] Permission denied: '/usr/local/airflow/logs/scheduler'
The reason I got that error is because I didn't create the initial 3 folders (dags, logs, plugins) before running airflow docker container. So docker seems to have created then automatically but the permissions were wrong.
Steps to fix:
Stop current container
docker-compose down --volumes --remove-orphans
Delete folders dags, logs, plugins
Just in case Destroy the images and volumes already created (in Docker Desktop)
Create folders again from command line
mkdir logs dags plugins
run airflow docker again
docker-compose up airflow-init
docker-compose up

Thanks in advance.
When I try to run CADRE plug-in it fails when trying to import 'MBI' module in 'CADRE.power' discipline:
Traceback (most recent call last):
File "C:\Users\Laurynas\CADRE\src\mppt.py", line 9, in <module>

from MBI import MBI
ModuleNotFoundError: No module named 'MBI'
Is this some kind of legacy python or OpenMDAO module? I was not able to find it in the web.
Yeah, MBI is a separate package, but you can find it here:
https://github.com/OpenMDAO/MBI
In summary: as far as I recall, after conda-installing fenics and sfepy (along with, through pip, some dependencies), I cannot run spyder:
$ spyder

Along the method of
https://www.scivision.co/fix-spyder-cxxabi-not-found-qt-error/
Would it be a terrible idea to simply copy
/usr/lib/x86_64-linux-gnu/libQt5WebKitWidgets.so.5
to
~/anaconda3/lib/
a la
cp /usr/lib/x86_64-linux-gnu/libQt5WebKitWidgets.so.5 ~/anaconda3/lib/
?
I'm paranoid about breaking something, is there a high probability of that happening?
Surely there's a better way to do this, no?
Thanks!
