I tried PIL (Python Image Library). Unfortunately, jython doesn't support it.
import Image
im = Image.open("tmp.png")
box = (100,200,300,400)
region = im.crop(box)
And the error message is
File "dota\PIL\Image.py", line 37, in __getattr__
raise ImportError("The _imaging C module is not installed")
ImportError: The _imaging C module is not installed
Is there other way?

Thanks in advance...
In windows 10 64-bit. There is some kind of solution with using
os.add_dll_directory(full_path)
before calling
self.__DTKLPR = cdll.LoadLibrary(DTKLPR5Lib)
but this solution is not working in Ubuntu. Because add_dll_directory is supposed to only windows. (Based on information in its documentation)
Basically, I am trying to generate simple word cloud using Python on Windows. Hence, I have installed wordcloud as:
pip install wordcloud
I am trying to run the simplest example from here as below:
import os
from os import path
from wordcloud import WordCloud
# get data directory (using getcwd() is needed to support running example in generated IPython notebook)
d = path.dirname(__file__) if "__file__" in locals() else os.getcwd()
# Read the whole text.
text = open(path.join(d, 'constitution.txt')).read()
# Generate a word cloud image
wordcloud = WordCloud().generate(text)
# Display the generated image:
# the matplotlib way:
import matplotlib.pyplot as plt
plt.imshow(wordcloud, interpolation='bilinear')
plt.axis("off")
# lower max_font_size
wordcloud = WordCloud(max_font_size=40).generate(text)
plt.figure()
plt.imshow(wordcloud, interpolation="bilinear")
plt.axis("off")
plt.show()
The error I got:

The PIL and Python versions on my side are:
from PIL import Image, ImageDraw, ImageFilter, ImageFont
print('PIL',PIL.__version__)
import sys
print(sys.version)
as:
PIL 9.2.0
3.7.13 (default, Mar 28 2022, 08:03:21) [MSC v.1916 64 bit (AMD64)]
Any suggestions ?
Thanks
On Windows 10, install the FreeType binding. Hopefully, it is resolved by re-installing the Pillow with disabling the pip cache as:
pip install freetype-py
pip uninstall pillow
pip install --no-cache-dir pillow
Once pillow is recompiled, everything worked properly for me!
In addition, the following check:
from PIL import features
print(features.check('freetype2'))
was False before the recent PIL re-installation. However, it is converted
into True after above listed steps. By the way, no need to reboot!
I am following the getting started guide for the Google Coral USB Accelerator and even though I was able to trick the install.sh file to install for RPI4

Any idea whay I could try?
I had the same problem but with an older Rpi 3. This is the solution I used. I don't think it's a make or break to complete the project:
$ sudo cp _edgetpu_cpp_wrapper.cpython-35m-arm-linux-gnueabihf.so _edgetpu_cpp_wrapper.cpython-37m-arm-linux-gnueabihf.so
Can you go through : https://github.com/google-coral/edgetpu-platforms ?
This repository holds auxiliary platform-related material related to Google Coral Edge TPU. Here you can find precompiled images, shared libraries and patches for using the USB Edge TPU accelerator on additional platforms to the main supported ones.
For convenience Google has uploaded prebuilt images for Raspberry Pi Zero, Pi 3 and Pi 4. Simply write the image to an sd card and boot up your Pi. The images contain several examples that should work out of the box.
Upon installing python xy 2.7.5 on my laptop, I tried to launch the Spyder IDE. This yielded the following error:

Using a python console, I was able to run python code as well as matplotlib and numpy code. Ipython works, however Ipython (Qt) does not work. what could be the reason for this?
The host OS is Windows XP.
This is actually a problem with the most recent builds of zeromq, which are messaging libraries that are required for IPython, and not with Spyder itself. The latest zeromq builds are not compatible with Win XP. This is a know issue with recent versions of Python(x,y) on Win XP which can be solved by following the guidance in this bug report.
It works by installing
https://pythonxy.googlecode.com/files/pyzmq-13.0.2-4_py27.exe
and
http://h5py.googlecode.com/files/h5py-2.1.3.win32-py2.7.msi

I am currently working with Gurobi solver using python. Previously, I have just been using a mix of a text editor and the terminal to write and run my models but I am currently experimenting with using Enthought Canopy Editor. I have a model that is works when I run in in the terminal using python model.py but when I try doing%run model.py in Canopy's iPython shell I get:
%run /home/cdhagmann/Copy/Code_Env/Farmer/model.py
---------------------------------------------------------------------------
ImportError Traceback (most recent call last)

My guess is that the terminal and Canopy look for modules in different places but I don't know how to rectify it. I found this reference on the Gurobi group site about Enthought Canopy and Gurobi on OS X 10.8 but didn't know how much those instruction would differ from doing it on Linux and even what he meant about installing Gurobi in Canopy's site-packages.
UPDATE: Based on information found the first link I clicked on, I did in fact leave the boxed clicked making Canopy my default directory. You have to manually prepend the PATH variable, which I missed them saying that I had to do. So I did that. I now have Canopy's version of iPython running in my terminal (check by using sys.path); however, I get a huge list of errors when I try run python.

If the terminal is correctly configured for Canopy Python, then python in terminal and Canopy Python should be looking for modules in the same places. If during installation, you disabled "make Canopy be default Python", or if you have not restarted terminal since installation, then it won't automatically be configured correctly.
These articles should help you understand and configure:
