I'm on OS X 10.10.4 with Macports and Anaconda (condo 3.15.1).
During the process of building the robotic simulator ARGoS,
https://github.com/ilpincy/argos3
we ran into runtime 'qt' issues running the ARGoS examples.
[FATAL] Can't load library "/usr/local/lib/argos3/libargos3plugin_simulator_epuck.dylib" even after trying to add extensions for shared library (dylib) and module library (so):
/usr/local/lib/argos3/libargos3plugin_simulator_epuck.dylib: dlopen(/usr/local/lib/argos3/libargos3plugin_simulator_epuck.dylib, 1): Library not loaded: #rpath/./libQtOpenGL.4.dylib
I learned that cmake found 'qt' within Anaconda which had runtime problems.
-- Found Qt4: /Users/davidlaxer/anaconda/bin/qmake (found version "4.8.6")
Next, I installed qt4-mac:

When I installed 'qt' with Macports, ipython qtconsole broke.

How is this supposed to work?

I am relatively new to Python and have developed an application for myself that I would like to make an executable. It uses multiple external libraries such as Pyqt5, sqlite3, and openpyxl. I am using pyinstaller to create the .exe - the installer fails with a message "nomodulefound xml.parser.expat" i've tried a few ways to include it in my package but to no avail.
here is a replicable py example:
from decimal import Decimal
import openpyxl # xl libraries
wb = openpyxl.load_workbook(r'C:\Users\jmstr\OneDrive\Documents\finproxlc.xlsx')
myint = Decimal("27")
print("hello")
any ideas?
Here is my pyinstaller cmd: pyinstaller C:\Users\usr1\IdeaProjects\GUIProjects\finpro.py -p C:\Users\usr1\venv\Lib\site-packages\openpyxl --hidden-import openpyxl --additional-hooks-dir C:\Users\usr1\venv\Lib\site-packages\openpyxl --collect-all xml.parsers.expat
Output of the pyinstall:

Seems like the installion of openpyxl was specific to my IDE (intelliJ) and i could not figure out how to change the spec file to get it to pick up but running this command resolved the issue:
python -m pip install openpyxl

Advice is welcome.
Thank you
I was able to reproduce the error and the reason seems to be the release of sqlalchemy 1.4 that introduces breaking changes. Airflow by default depends on the latest version of sqlalchemy, but cannot work with version 1.4. A workaround is to downgrade sqlalchem to a version < 1.4.0:
pipenv uninstall sqlalchemy
pipenv install 'sqlalchemy < 1.4.0'
When installing Airflow fresh:
pipenv install 'sqlalchemy < 1.4.0' apache-airflow
Please use below
pip install "apache-airflow[celery]==2.2.2" --constraint "https://raw.githubusercontent.com/apache/airflow/constraints-2.2.2/constraints-3.6.txt"
It will definitely work.

I just started the PyTorch-Tutorial Deep Learning with PyTorch: A 60 Minute Blitz and I should add, that I haven't programmed any python (but other languages like Java) before.
Right now, my Code looks like
import torch
import torchvision
import torchvision.transforms as transforms
import matplotlib.pyplot as plt
import numpy as np
print("\n-------------------Backpropagation-------------------\n")
transform = transforms.Compose(
[transforms.ToTensor(),
transforms.Normalize((0.5, 0.5, 0.5), (0.5, 0.5, 0.5))])
trainset = torchvision.datasets.CIFAR10(root='./data', train=True,download=True, transform=transform)
trainloader = torch.utils.data.DataLoader(trainset, batch_size=4, shuffle=True, num_workers=2)
testset = torchvision.datasets.CIFAR10(root='./data', train=False, download=True, transform=transform)
testloader = torch.utils.data.DataLoader(testset, batch_size=4, shuffle=False, num_workers=2)
classes = ('plane', 'car', 'bird', 'cat', 'deer', 'dog', 'frog', 'horse', 'ship', 'truck')
dataiter = iter(trainloader)
images, labels = dataiter.next()
def imshow(img):
img = img / 2 + 0.5
npimg = img.numpy()
plt.imshow(np.transpose(npimg, (1, 2, 0)))
imshow(torchvision.utils.make_grid(images))
print(' '.join('%5s' % classes[labels[j]] for j in range(4)))
which should be consistent with the tutorial.
If I execute this, I'll get the following error:

I already downloaded the *.py and *.ipynb.
Running the *.ipynb with jupyter works fine (but I don't want to programm in the juniper web-interface, I prefer pyCharm) while the *.py in the console (Anaconda prompt and cmd) fails with the same error.
Does anyone know how to fix this?
(I'm using Python 3.6.5 (from Anaconda) and pyCharm, OS: Win10 64-bit)
Thanks!

Update:
If it is relevant, I just set num_workers=2 to num_workers=0 (both) and then it'll work.. .
Check out the documentation for multiprocessing: programming guidelines for windows. You should wrap all operations in functions and then call them inside an if __name__ == '__main__' clause:
# required imports
def load_datasets(...):
# Code to load the datasets with multiple workers
def train(...):
# Code to train the model
if __name__ == '__main__':
load_datasets()
train()
In short, the the idea here is to wrap the example code inside an if __name__ == '__main__' statement.
Because of different implementation of multiprocessing in Windows, you need to wrap your main code with this block:
if __name__ == '__main__':
For more info, you can check the official PyTorch Windows notes.

from woocommerce import API
ImportError: No module named woocommerce
It seems like you do not have installed woocommerce REST api on your system.
install woocommerce using your terminal. here is the command
sudo pip install woocommerce
EDIT:
Open python prompt in terminal
$ python
Python 2.7.3 (default, Mar 13 2014, 11:03:55)

Type "help", "copyright", "credits" or "license" for more information.
>>> from woocommerce import API
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: No module named woocommerce
If it says No module named woocommerce means you have some installation issue with woocommerce.
I was facing same problem while installing woocommerce connector in odoo. After that i have installed woocommerce module by
pip install woocommerce. I was working on windows platform.
I was getting same problem after successfully installing woocommerce python module.
Here Problem is odoo is not finding woocommerce in it's addon folder.
So solution is here :
open folder "C:\Python27\Lib\site-packages".
This is the path where python modules are installed. From this folder find the folder 'woocommerce'.
copy this folder and put this in odoo server path which is
"D:\Odoo 8.0-20160107\server" .
Now restart odoo
Hope this will help you.
