I've been trying to get Kivy to work on my Mac (Lion), but I've been encountering issues. I followed the instructions on the Kivy site, and since Kivy 1.8 supports Python 3, I wanted to run it with 3.3, and I finally got that to work, by editing the kivy file to point to 3.3 instead of 2.7. I tried drop a .py program on the Kivy icon, the app opened but nothing happened. So I tried to run it from the command line. It opened 3.3, as expected, but I got the following error.
Python 3.3.4 (default, Mar 6 2014, 20:14:14)

I have no idea why I would get this error, since I previously installed pygame for 3.3, and import pygame or from pygame.base import * work error free. Would this issue with pygame explain why .py files fail to execute when I drop them onto the Kivy icon?
Kivy.app and all the dependencies included in it is compiled with and for Python 2.7. You cannot use it for 3.3.
If you want to try Kivy with 3.3, you also need to compile Kivy yourself :)

I have created a virtual ubuntu machine and installed ALLENNLP,
In that and tried example from ALLENNLP demo website
I have executed below code
from allennlp.predictors.predictor import Predictor
import allennlp_models.tagging
predictor = Predictor.from_path("myLocalPath/stanford-sentiment-treebank-roberta.2021-03-11.tar.gz")
predictor.predict("a very well-made, funny and entertaining picture.")
which gave me below error.
>>> predictor.predict("a very well-made, funny and entertaining picture.")
Traceback (most recent call last):

File "/home/.local/lib/python3.8/site-packages/allennlp_models/classification/dataset_readers/stanford_sentiment_tree_bank.py", line 114, in text_to_instance

AssertionError
But when I executed below code
from allennlp.predictors.predictor import Predictor
import allennlp_models.tagging
predictor = Predictor.from_path("myLocalPath/sst-roberta-large-2020.06.08.tar.gz")
predictor.predict("a very well-made, funny and entertaining picture.")
It worked.
Only difference between above two code is version of roberta-large train data
I have installed latest version of ALLENNLP in my virtual machine
I don't have NVIDIA graphic card in my virtual machine could this be a reason?
But then how come other version is working?
Please help
Allen NLP version was the issue it was ALLENNLP 2.1.0, It worked with ALLENNLP version 2.4.0.
Use command "pip install allennlp"
and then "pip install allennlp-models"
instead of "pip install allennlp==[some version] allennlp-models==[some version]"
or make sure you have version greater than or equal to 2.4.0.
I will work with mysql, but it gives this error anyway. I did delete the module but it did not change, I loaded it differently, I could not solve the modules.
Traceback (most recent call last):
File "C:\Users\INAL\Desktop\Son Scriptler\mysql\mysql.py", line 1, in <module>
import mysql.connector
File "C:\Users\INAL\Desktop\Son Scriptler\mysql\mysql.py", line 1, in <module>
import mysql.connector
ModuleNotFoundError: No module named 'mysql.connector'; 'mysql' is not a package
You might not have the mysql-connector did you try installing it using pip?
pip3 install mysql-connector
The problem was that my project name was mysql.py and I solved the problem by changing the project name.
I wouldn't call myself a programmer and am unfamiliar with Mac and Linux, so any links or pointers to additional background would help greatly. I've started with the most basic pygame I could google, (from https://realpython.com/pygame-a-primer/). The test.py and test.app runs on my VM but not on anyone else's real Macs.
test.py file
import pygame
pygame.init()
screen = pygame.display.set_mode((400, 300))
done = False
while not done:
for event in pygame.event.get():
if event.type == pygame.QUIT:
done = True
pygame.display.flip()
setup.py file
from setuptools import setup
APP = ['test.py']
DATA_FILES = []
OPTIONS = {}
setup(
app=APP,
data_files=DATA_FILES,
options={'py2app': OPTIONS},
setup_requires=['py2app'],
)
command to create the test.app
$ python3 setup.py py2app
The test.app runs fine on the VM, but whenever the test.app runs on a real Mac (tested 2, one ran on Catalina ver???) this error message appears:
Traceback (most recent call last):

Any ideas or pointers would be greatly appreciated. The actual program is an OhHell card game which supports Windows clients (via pyinstaller), but I'm also trying to support a Mac client to play with my friends on a Mac. Similar to the test.py and test.app (ohhell.py and ohhell.app) runs on the VM Mac but same issue/error occurs with real macs. I've just included the simplest code snippet that I was able to google that reproduced the exact error message.

Workaround Solution: Linking to a dynamic library on a Mac with full path and What path does #loader_path resolve to?. Using the '$ install_name_tool -change "#loader_path/.dylibs/libSDL-1.2.0.dylib" "/Applications/test.app/Contents/Frameworks/libSDL-1.2.0.dylib" base.so' resolved the Library not loaded: loader_path/.dylibs/libSDL-1.2.0.dylib errors. I assume this hard codes the path, but with my friends it's fine to tell them to make sure it resides in the /Applications folder.
However a secondary problem came up, 'pygame.error: File is not a Windows BMP file'. I used py2app, so the pygame delete and reinstall threads didn't seem like a feasible solution (pygame unnecesary w/py2app), so switching the images to uncompressed bitmap (256 colors) worked.
For those curious, I did try Pyinstaller for Mac but that presented a whole new set of problems.
how to convert HTML to PDF in Python3?
Xhtml2pdf does not work in Python3, got error:
import xhtml2pdf.pisa as pisa
Traceback (most recent call last):

The best that I found by far is weasyprint.
From the documentation:
from weasyprint import HTML
HTML('http://weasyprint.org/').write_pdf('/tmp/weasyprint-website.pdf')
and it really works that easy. Saved me tons of time (after I wasted time trying to get xhtml2pdf and others to work in python 3 but failed.
I had the same error. Apparently for now xhtml2pdf has Python3 support only in its prerelease version - 0.2b1 (for more info see https://pypi.python.org/pypi/xhtml2pdf). I’ve solved the problem by uninstalling the previous xhtml2pdf version and installing the prerelease version
pip install --pre xhtml2pdf

I had this error with fabric. The error message was the same:
ImportError: No module named exceptions
It turned out to be my fabric was out of date. The error was resolved by upgrading fabric to the latest version (1.10) with:
$ sudo pip install fabric --upgrade
For your information, I am running Ubuntu 12.04 64-bit with Python 2.7.3
Exceptions should be a python file in a directory called billiard, for example, you create a file called exceptions.py and add the classes and methods that you need .. this can work around the problem.
You should follow kitsune installation process described in http://kitsune.readthedocs.org/en/latest/hacking_howto.html
There is a link to separate chapter on vendor-packages http://kitsune.readthedocs.org/en/latest/vendor.html#vendor-chapter. You should install all the vendor packages needed by kitsune including billiard and celery (your errors).
