Android QPython pyttsx requiring ctypes - ctypes

I have used pyttsx on my desktop but new to using it on an android mobile phone.
I recently downloaded Pyttsx
pip install pyttsx
I ran a little tester on the QPython console but came across an error I haven't seen before.
>>>import pyttsx
>>>engine = pyttsx.init()
the last line of error states:
ImportError: cannot import name c_wchar_p
So I tried to import ctypes
>>>>import ctypes
>>>>import pyttsx
>>>>engine = pyttsx.init()
But had the same error occur. Any ideas?
Thanks

ModuleNotFoundError: No module named 'fastai.vision'

I am trying to use ImageDataBunch from fastai, and it worked fine, but recently when I ran my code, it showed this error ModuleNotFoundError: No module named 'fastai.vision'
Then, I upgraded my fastai version pip install fastai --upgrade. This error got cleared but landed in NameError: name 'ImageDataBunch' is not defined
Here's my code:
import warnings
import numpy as np
from fastai.vision import *
warnings.filterwarnings("ignore", category=UserWarning, module="torch.nn.functional")
np.random.seed(42)
data = ImageDataBunch.from_folder(path, train='.', valid_pct=0.2,
ds_tfms=get_transforms(), size=224, num_workers=4, no_check=True).normalize(imagenet_stats)
How can I fix this?
I actually ran into this same issue when I started using Colab, but haven't been able to reproduce it. Here was the thread describing what I and another developer did to troubleshoot: https://forums.fast.ai/t/no-module-named-fastai-data-in-google-colab/78164/4
I would recommend trying to factory reset your runtime ( "Runtime" -> "Factory Reset Runtime")
Then you can check which version of fastai you have (you have to restart the runtime to use the new version if you've already imported it)
import fastai
fastai.__version__
I'm able to run fastai.vision import * on fastai version 1.0.61 and 2.0.13
In Google Colab:
Upgrade fastai on colab:
! [ -e /content ] && pip install -Uqq fastai
Import necessary libraries:
from fastai.vision.all import *
from fastai.text.all import *
from fastai.collab import *
from fastai.tabular.all import *
Get the images and annotations:
path = untar_data(URLs.PETS)
path_anno = path/'annotations'
path_img = path/'images'
print( path_img.ls() ) # print all images
fnames = get_image_files(path_img) # -->> 7390 images
print(fnames[:5]) # print first 5 images
The solution that worked for me is to copy to (connect) my google drive & then run the cells. Source
You might have installed the older version of fastai. You need to upgrade to fastaiv2. You can upgrade fastai by using pip as shown below.
!pip install fastai --upgrade
Also check your fastai version using
import fastai
print(fastai.__version__)

pygame py2app Library not loaded: #loader_path/.dylibs/libSDL-1.2.0.dylib

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.

Python3 html to pdf

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):
File "", line 1, in
File "/home/hound/test/python/test_env/lib/python3.4/site-packages/xhtml2pdf/init.py", line 41, in
from xhtml2pdf.util import REPORTLAB22
File "/home/hound/test/python/test_env/lib/python3.4/site-packages/xhtml2pdf/util.py", line 302
raise Exception, "box not defined right way"
^
SyntaxError: invalid syntax
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

Running Google's DeepDream on Windows with CUDA: ImportError DLL load failed [duplicate]

I have build .dll of _caffe.cpp on Windows (Release, x64).
I changed extension .dll to .pyd and trying to import it in python:
import caffe
File "\caffe-master\python\caffe\__init__.py", line 1, in <module>
from .pycaffe import Net, SGDSolver
File "\caffe-master\python\caffe\pycaffe.py", line 13, in <module>
from ._caffe import Net, SGDSolver
ImportError: DLL load failed: The specified module could not be found.
What does it mean, some module of dependencies missing which was included in project in Visual Studio, where I build this dll?
You need to add Python Caffe to PYTHONPATH. For example:
export PYTHONPATH=$PYTHONPATH:/home/username/caffe/python
For windows :
Adding /caffe/Build/x64/Release/pycaffe to system path(path) works for me, and I think the best way to do it is :
New a system variable : PYTHON_PKG = /caffe/Build/x64/Release/pycaffe;
Include PYTHON_PKG in path : path = %PYTHON_PKG%; %OtherDirs%
After I did this, I get PKG missing google.internal, then I did pip install google.internal in CMD. It works.
Once you have a compiled and built caffe, try
echo 'export PYTHONPATH=/path/to/caff-dir/python'
Also, you may need to run following:
pip install -r requirement.txt

Kivy pygame error

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 :)
