I installed airflow: pip install apache-airflow, airflow initdb and started the airflow webserver airflow webserver -p 8080 but when I try to open the home page, I keep getting the error message:
UnicodeDecodeError: 'ascii' codec can't decode byte 0xe2 in position 0: ordinal not in range(128)
I even tried a different version 1.10.1, I got the same issue.
Here's the full stacktrace:

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

Based on the bug report from github, this is a unicode issue in configuration file.
Solution #1 - You need to generate an UTF-8 locale and launch certbot with it.
Like this:
LANG=en_US.UTF-8 certbot […]
Or, Solution #2 - replace unicode characters in nginx config
You can find the offending line with following command and delete it.
grep -r -P '[^\x00-\x7f]' /etc/apache2 /etc/letsencrypt /etc/nginx
And rerun certbot command.

Appreciate your advice.
The interesting part of the error is.

I guess you Jupyter kernel is referencing the old installation of R that you have updated.
The first thing to do is to check what is defined in your R kernel.
Check kernel
# list all kernel
jupyter kernelspec list
#Available kernels:
# ir /opt/conda/share/jupyter/kernels/ir
# ...
You should have an ir kernel.
Check the content of the kernel definition, for example:
$ cat /opt/conda/share/jupyter/kernels/ir/kernel.json
# {"argv": ["R", "--slave", "-e", "IRkernel::main()", "--args", "{connection_file}"],
# "display_name":"R",
# "language":"R"
# }
If the command in argv is incorrect you can remove an reinstall the kernel.
Remove and reinstall the kernel
See the IRkernel installation documentation for more information.
$ jupyter kernelspec remove ir
$ R
# Install IRkernel
> install.packages('IRkernel')
# Or update it if already installed
> update.packages('IRkernel')
# Install the kernel
> IRkernel::installspec()
# Or alternatively if you want to install it system-wide
> IRkernel::installspec(user = FALSE)
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):

I learned that cmake found 'qt' within Anaconda which had runtime problems.
