I am trying to open camera with the picamera module in my Raspberry pi B+ with has Raspbian 64 bit OS installed in it. I get this error:

The camera is enabled (I tried to capture the camera with opencv and it worked).
I tried sudo rpi-update as well and it says that my firmware is already up to date.
Tried sudo apt update and sudo apt upgrade but none of them solve the above issue.
I tried sudo ldconfig -p | grep mmal as well and it outputs:
libmmal_vc_client.so (libc6) => /opt/vc/lib/libmmal_vc_client.so
libmmal_util.so (libc6) => /opt/vc/lib/libmmal_util.so
libmmal_core.so (libc6) => /opt/vc/lib/libmmal_core.so
libmmal_components.so (libc6) => /opt/vc/lib/libmmal_components.so
libmmal.so (libc6) => /opt/vc/lib/libmmal.so
Any suggestions on what I can do to solve this error? Thanks!
I just found out that picamera is still not supported for Raspbian 64 bit OS.
https://github.com/raspberrypi/firmware/issues/1558#issuecomment-983483179
So we could probably use libcamera (didn't try it yet) or opencv (tried and works fine)

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'm working with Python 2.6.6. Everything was working fine until I wrote
pip install --upgrade --user pip
Then the terminal say:

After I tried to install SciPy with:

But now I get:

Any recommendations to solve the problem?
Try
easy_install-2.6 --upgrade 'setuptools<37' 'pip<10'
If it doesn't work install pip from https://bootstrap.pypa.io/2.6/get-pip.py :
curl https://bootstrap.pypa.io/2.6/get-pip.py -o get-pip.py # or wget -O
python2.6 get-pip.py
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.
Im trying to install aws for the mac command line, I guess I dont understand what I need to do I installed the aws bundle with wget on the terminal, unziped it did everything, but when I need to configure my credentials nothing comes up when I put aws configure..

Installing AWSCLI in Windows Machine
I had similar issue with Windows 10 (64 bit). Python 3.5 and Python 2.7 are installed in my PC. I was getting ImportError: No module named awscli.clidriver.
Then I added %USERPROFILE%\AppData\Roaming\Python\Python35\Scripts in environment path variable and removed Python 2.7 from the environment path variable. Now I can successfully use awscli.
I have created a step by step AWSCLI installation guide in this Github repository: https://github.com/arsho/installation/tree/master/awscli_installation.
I had to install EKS supported version and I ended up getting it to work with ignoring six:
$ pip3 install awscli --ignore-installed six
In my case nothing worked, untill i gave more permissions, i run aws command with a non root user
chown amzadm.root /usr/bin/aws
chown amzadm.root -R /usr/lib/python2.6/site-packages/
chown amzadm.root -R /usr/lib/python2.6/site-packages/awscli/
I fixed this by adding a line to the 'aws' script just before the import (line 19). So now the file reads:
sys.path.append('/Users/<username>/.local/lib/aws/lib/python2.7/site-packages/')
import awscli.clidriver
This work for me. In /.barshrc file
export AWS_DEFAULT_OUTPUT="json"
I'm brand new to Python programming and trying to get myself a functional base from which I can run things like the IPython Notebook which looks pretty exciting.
Thus far I have both Python 2.7 and 3.3 from python.org installed in OS X 10.6 (Snow Leopard) as well as ActiveTcl 8.5.13. Almost everything that I've tried thus far works as expected. I'm focused on learning 3.3, but want to have the option of using 2.7 too. I read up in several documents that I need to start gaining access to PyPI packages using a Python package manager and that distribute is the one I should use for 3k. So I installed that according to the documentation I found and it seemed to work fine.
I also installed pip as directed, and a number of others.
At this point, I have:
$ pip freeze
distribute==0.6.34
ipython==0.13.1
nose==1.2.1 (installed after IPython)
pexpect==2.4 (installed after IPython)
pyflakes3k==0.4.3
readline==6.2.4.1 (installed after IPython)
At this point, I'm doing this from ipython.org guidance
And when I did $ easy_install pexpect, I got a bunch of errors:

That looks bad to me (although I don't yet have the expertise to really interpret it), and so I'm not sure if I have a complete install of pexpect.
After installing nose (before pexpect as per URL above), I tried running iptest and iptest3 from the command line, and both failed to find the command, but after I did easy_install ipython again (after nose), I noticed that this install added iptest3 (as well as ipcluster3 and a few other scripts) to my path, and now my bash shell can find iptest3, but when I run it, I get some more bad-looking output:
$ iptest3

After doing all that, I noted that my /Library/Frameworks/Python.framework/Versions/Current had been pointing to 2.7, and I guessed that that might be related to my problems and changed the symbolic link to point to 3.3, but iptest3 still fails with the error above.
Any other thoughts on what to do to fix this? It's clear that iptest is pretty important to doing anything else (like IPython Notebook) I want to do.
There is a py3-compatible fork of pexpect called pexpect-u (the u is for unicode, the main difference between the two). You need this to run the pexpect-based parts of IPython on Python 3.
Should be a simple
pip install pexpect-u
side note: pexpect-u is by IPython developer Thomas Kluyver, who did most of the heavy lifting bringing py3 compatibility to IPython.
