QUESTION
I am trying to build an app from a python file (Mac OS) using the py2app extension. I have a folder with the python file and the "setup.py" file.
- I first tested the app by running
python setup.py py2app -A
in the terminal and the dist and build folder are successfully created and the app works when launched. - Now when I try to build it non-locally by running the command
python setup.py py2app
in the terminal, there are various "WARNING: ImportERROR" messages while building and finally aerror: [Errno 2] No such file or directory: '/opt/anaconda3/lib/python3.8/site-packages/rtree/lib'
error.
How can I fix this? I've tried to delete anaconda fully as I don't use it but it seems to still want to run through it. Additionally, I have tried to run the build command using a virtual environment but I end up having even more import errors.
*I Left out a lot of the "skipping" and "warning" lines using "..." for space
ANSWER
Answered 2022-Mar-13 at 16:13The error error: [Errno 2] No such file or directory: '/opt/anaconda3/lib/python3.8/site-packages/rtree/lib'
was caused by py2app trying to build the program bundle using a non-existent interpreter. This means that even if you try to uninstall a manager like Anaconda, it still has option logs somewhere on your mac.
The fix:
- Open the terminal and type the command
type -a python
.
- You will see similar lines

I am trying to deploy my first web app on Heroku however I am getting a PyObjc error while pushing the code. I am doing this on a Mac Machine. This predictive application is developed using Flask. I do not know why this error is occurring as I do not have the PyObjc in my requirements.txt

appears to be Apple-only:
Simple package for registering an app with apple Launch Services to handle UTI and URL. See Apple documentations for details.
I suspect you don't need that, either. Did you create your requirements.txt
from a pip freeze
? There's likely a bunch of stuff in there you don't need.
I suggest you review that file and remove anything you aren't directly depending on. pip
will find transitive dependencies (dependencies your dependencies depend on) and install them automatically.
Prune that file, commit, and redeploy.

I am attempting to install PyGMO on Mac OS X 11.2.2 (with Anaconda which I reinstalled so the Anaconda Navigator is now upgraded to 2.0.1.)
After the installation starts, it collects package metadata and reports it found package conflicts. How can I solve the conflict so that I can run PyGMO?
Here is the start:
...ANSWER
Answered 2021-May-11 at 00:21There are two possible states:
Conda solver is correct. The previous package constraints you have in the environment are incompatible with installing
pygmo
. In that case, you either need to track down the conflicting constraints and try to manually loosen them (not recommended for Anaconda base), or you need to make a new environment:

I've built this telegram bot yesterday, and it ran smoothly on Heroku.
However, today I added a new package python-google-places

is redundant for Heroku. But it is ok to use it for development.
Most probably that you are erasing it from dependencies using pipenv
. Try to add to Pipfile
and then do pip freeze
QUESTION
I am writing a program in Python to run on a Raspberry Pi in order to control my Wurlitzer jukebox. The program current accepts the codes for "record selection" (A1, B1, C4, etc.), add those codes to a playlist, and executes the list. My issue is that once a song starts, I would like to be able to press a button ("Y" in the current code) to skip the currently playing song. I can't get this to work.
If I use "player.next()" I get an error: 'MediaPlayer' object has no attribute 'next'.
I tried to stop the player and restart it (thinking it would pick up the next song in the Playlist. This doesn't even stop the player.
I do not want to use subprocess if I can avoid it. I'd like to figure out a way within Python to do the skipping. How would one accomplish this?
...ANSWER
Answered 2021-Feb-24 at 10:19The way you have it coded, I expect you'd have to stop it, remove the current media from the list, then re-start it.
However you may be better off running with a media_list_player
, see below for a bare bones version. Note, I'm on Linux and had to hack some code to get the key input, rather than using a specific library or spend time on it, but it should give you enough to work with.
Edit
I apologise, there is a much simpler method when using a media_list_player
, although if you want finer control you should use the media_list_player
where you control the list's index or for full control use a media_player_new()
but that's beyond the scope of this question. (I'll leave the original answer below this code, as it may be useful)

Created a new compute instance in Azure ML and trained a model with out any issue. I wanted to draw a pairplot using seaborn

I ran !conda list

ANSWER
Answered 2020-Sep-07 at 04:17I just did the following and wasn't able to reproduce your error:
- make a new compute instance
- open it up using JupyterLab
- open a new terminal
conda activate azureml_py36
conda install seaborn -y
- open a new notebook and run
import seaborn as sns
- Are you using the kernel,
Python 3.6 - AzureML
(i.e. theazureml_py36
conda env)? - Have you tried restarting the kernel and/or creating a new compute instance?
QUESTION
I'm going to use rasterio in python. I downloaded rasterio via
...ANSWER
Answered 2020-Sep-22 at 05:37I've got some experience with rasterio, but I am not nearly a master with it. If I remember correctly, rasterio requires you to have installed the program GDAL(both binaries and python utilities), and some other dependencies listed on the PyPi page. I don't use conda at the moment, I like to use the regular python 3.8 installer with pip. Given what I'm seeing with your installation, I would uninstall rasterio and follow a different installation procedure.
I follow the instructions listed here: https://rasterio.readthedocs.io/en/latest/installation.html
This page also has separate instructions for those using Anaconda.
The GDAL installation is by far the most annoying but once it's done, the hard part is over. The python utilities for both rasterio and gdal can be found here:
https://www.lfd.uci.edu/~gohlke/pythonlibs/#gdal
The second link is also provided on the PyPi page but I like to keep it bookmarked because there's a lot of good resources there!
