🎉 Thank you for informative video. I have a question about: Is it compatible with Raspberry Pi 4B 8 GB?

with running the image classifier i get this error meesage Jennypi@Jenny:~/Python-3.9.19/pycoral $ python3 examples/classify_image.py \ --model test_data/mobilenet_v2_1.0_224_inat_bird_quant_edgetpu.tflite \ --labels test_data/inat_bird_labels.txt \ --input test_data/parrot.jpg Traceback (most recent call last): File "/home/Jennypi/Python-3.9.19/pycoral/examples/classify_image.py", line 36, in <module> from PIL import Image ModuleNotFoundError: No module named 'PIL'

Nice writeup!

thanks for sharing! but how does it get integrated into a backend python program for example?

is it not using the gpio pin in its connection?

love to visit Key West and Lower Silesia

thanks

This all doesn't work now? Can you please test it all again?

What a depressing afternoon. I thought I'd try a coral TPU out. I ran into the python issues and ended up setting up a python 3.9 docker container for the job. Despite trying everything under the sun every attempt leads to a seg fault as it tries to initialise the interpreter.

is it possible to write a script that keeps different screws or small objects apart?

Guys donot run this 2. Update the python3 symlink: If you want the system to use Python 3.9 by default when you type `python3`, update the symlink: sudo update-alternatives --install /usr/bin/python3 python3 /usr/local/bin/python3.9 1 It might break your system package.

When I run sudo apt-get install libedgetpu1-std I get this error:ModuleNotFoundError: No module named 'apt_pkg' Edit: Turns out that this isn't a problem. I did get an error about the numpy version when trying to run inference but 'pip3 install --upgrade numpy==1.19.3' fixed that. Now it's working great! Thank you for this video I'd been struggling for days.

Nice content, wondering are you interested in a potential video collaboration? (PCBWay zoey)

Can we detect different people faces? Can we open doors based on faces? Can we write a script to make decisions?

Fantastic video! thanks so much!

Good luck and have nice stay in PL!

Creative:)

I'm not sure how common axial lead capacitors are these days. I guess you could use modern through-hole electrolytic capacitors to replace the bad ones, but you might end up needing extension wires, and even if you do not, it might ruin the look. I suggest you replace the bad components with new ones, put the new ones on the underside of the board, and hot-glue the dead old ones on top of the board.

Why its not working anymore

The OrangePi boards come with an NPU on board. RPI is really lacking in hardware

Even now i would love to get my hands on a electronics laboratory like that. Its actually a lot better than the unit i have! Top video 😊

My brother had an almost identical one - I played with it a lot as a 10 year old kid. That's how my career in electronics started. I didn't grasp algebra or Ohm's law yet, but still, I learned schematics and built circuits. We didn't have Commodores and all the fun '80s Western stuff until the '90s, after People's Republic of Poland fell, and our country started opening up to foreign tech, clothes, food and other consumer goods - those were wild times. Our industry didn't survive the disruption in economy, factories were going bankrupt or were bought out by international corporations, usually as a hostile takeover. Unemployment and inflation soared. Lots of people came out destroyed from this era, but some entrepreneurial types made fortunes.

Nice. I've had similar kits.

I still have one in the attic.

Ex pat? You mean inmigrant don't You?

Why spoil a good video with silly music?

I was never a fan of such electronics kits. I had a similar RadioShack kit from the very early 2000s. I much prefer building on breadboards and perfboards, since they're more permanent.

Board placing is well done (like caps and antenna rod near each other), but the speaker terminals are STUPID (on the right instead of the left?).

You must be Russian, you said "the relay" instead of the correct "a relay" :)

All the transistors are germanium low-frequency with 1MHz transition frequency. The IC has inside analogs of BC546 (soviet KT315) or MMBTH10. I had some details from these in 1990x when I was a scoolboy

That is pretty cool. Radio Shack in Canada sold a similar kit in the late 70s. This is pretty cool that they create simple amplifiers to illustrate how the transistor is used. A little non-intuitive that in the PNP circuits that have the + side of the battery at the bottom of the diagram, not the top. I believe in Western electronics, the negative voltage is always at the bottom of the schematic.

Much better than the kit I had . A dc motor in a little race car, and a light bulb.

Hello. My family came from Breslau. Trying to learn family info is impossible.

Excellent ! can it detect patterns like aruco markers or qr code pattern ?

This ONLY works for python version 3.6 - 3.9. NO the "pyenv" doesn't solve the problem. If your OS natively runs with python 3.6 to 3.9 then opt USB Coral, otherwise for newer OS better look for something else. Coral dev team already made enough money out of this product, and are NOT willing to provide support to fix any issues.

Big thanks for taking the time to create this video , easy to follow process and sharing the info. My USB Coral is now working with the Pi5 🙂 😁👍

Lol, can you take control of my pc and install it for me? i desperately need it

Cool demo! Does this mean that you can use two different versions of python in your Project1 as well? Say you have another Python script that relies on Python2.7 and that script is also a part of this "Project1" such that it's executed first, say, to recognize something, then, once it's finished, the next script is executed, which uses python3 to perform a different type of computer vision task. Have you done such a task before?

Great video my friend! I am enjoying your channel and learning tons... thank you! Question, why didn't you simply take the same approach as you did with the other video (from two months ago) where you used pyenv in your Ubuntu to manage the python versions? Is it not possible here, or maybe you just want to show multiple solutions? I am trying to follow along and I have a CM4 module so hopefully I have as much fun as you!

Thank you for putting this together! I had spent more than 2 days struggling to get my setup up and running and was starting to look for alternatives to Coral. I'm excited to finally have this up and running!

I get this when I try to run an example: /Python-3.9.19/coral/pycoral $ python3 examples/classify_image.py \ --model test_data/mobilenet_v2_1.0_224_inat_bird_quant_edgetpu.tflite \ --labels test_data/inat_bird_labels.txt \ --input test_data/parrot.jpg A module that was compiled using NumPy 1.x cannot be run in NumPy 2.0.0 as it may crash. To support both 1.x and 2.x versions of NumPy, modules must be compiled with NumPy 2.0. Some module may need to rebuild instead e.g. with 'pybind11>=2.12'. If you are a user of the module, the easiest solution will be to downgrade to 'numpy<2' or try to upgrade the affected module. We expect that some modules will need time to support NumPy 2.

I tried the coral usb on windows and Ubuntu nothing 😢 I'm returning mine I've been trying for over a week now

The problem with all these TPUs is that you can only run the models from the examples. So far, I didn't manage to find a tutorial on how to design and train on an Nvidia card a CNN model that will run on Coral or any other Pi TPU

I badly need the coral dev board right now for my ADAS project but the 4GB version is out of stock

Does it matter what kernel version or is 6.1 good enough?

Very good content, I'm glad to know that there are people uploading useful content like this. I look forward to seeing you implementing a yolo model with tflite and GCoral!

Hello Chief im new to this i wanna buy one Can you try a pre-trained roboflow model id like to see you? performance my surfaces pro 9 only get 6fps at 640x640 at 18fps at 100x100

can raspberry pi 5 and google coral usb run yolo models (like yolov8) well? I'm really looking forward to the next video if you are pleased.
