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

I cannot run the example with the image classification. When I run the sample, I get this:

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.

I can use the nrf24l01 wireless module just fine with a Raspberry Pi Pico, but when I try to compile the same code on the Raspberry Pi Pico W, it fails to recognize the device. I am using this library, and I get this error:
Traceback (most recent call last):
File "<stdin>", line 31, in <module>
File "nrf24l01.py", line 78, in __init__
OSError: nRF24L01+ Hardware not responding
The boards are supposed to have the same footprint, so what is the difference here? How can I use these modules with the Pico W?
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_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)
I'm using a raspberry pi pico to read data from a SHT3x sensor using the I2C protocol. I'm quite new to (micro)python so I used this example. This example is for a regular Raspberry Pi since I didn't find any for the Pico. However, the SMBus library is not found. I assume it is just not available for micropython (I have version 1.17).
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: no module named 'smbus'
There seems to be only one micropython wrapper for SMBus (as far as I found), this one. When I use this wrapper, the problem I have and don't understand is the following error:
Traceback (most recent call last):
File "<stdin>", line 8, in <module>
File "usmbus.py", line 50, in write_i2c_block_data
TypeError: object with buffer protocol required
Refering to this line function: writeto_mem(addr, register, data) (documentation).
The data that I pass in is as follows
addr = 0x44
register = 0x2C
data = [0x06]
I understood that it has something to do with framebuffer in micropython not being supported, but I don't understand how to fix it. Can someone help me out? Or suggest me other solutions?
If the sensor supports I2C, you should be able to use the builtin MicroPython I2C support.
I also found a library for the SHT3x, by searching on the MicroPython forum.
I am a new user for Ubuntu16.04 as well as caffe.
Few days ago I was working with Intel Movidius with the ncappzoo thingy and it worked. Afterward I tried to download the toolkit and API to play with. As I was verifying the installation of the toolkit, I found that the function importing caffe can no longer work. It keeps giving me this error.
I tried googling but find no solution. The $PYTHONPATH was check and verified. I also reinstalled the scikit-image.
Here's the block of gibberish thingy it bounced back to me :

Any idea what went wrong?
We are able to make use of all the apps/networks available from ncappzoo without any issues.
Our configuration is as follows:
movidius#osboxes:~$ python --version
Python 2.7.12
movidius#osboxes:~$ echo $PYTHONPATH
:/opt/movidius/caffe/python
movidius#osboxes:~$ lscpu | grep "Model name"
Model name: Intel(R) Core(TM) i5-5300U CPU # 2.30GHz
movidius#osboxes:~$ lsb_release -a
No LSB modules are available. Distributor ID: Ubuntu Description: Ubuntu 16.04.3 LTS Release: 16.04 Codename: xenial
Assuming that you have downloaded the ncsdk and then installed it. If not,
First we need to install 'ncsdk' which enable rapid prototyping, validation, and deployment of deep neural networks
please follow the links mentioned below to install ncsdk
(It includes software tools, API and examples)
https://developer.movidius.com/start
https://movidius.github.io/ncsdk/install.html
once the ncsdk installation is suceessfull, then you can make use of all the apps/networks available in ncappzoo.
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:
