Flask

[Logan-Orr]

So, this project has been working fine, but one day i turned it on and it did not boot, it was stuck at the white screen, I reinstalled the software, it worked. But, I still had to update it, I updated it and tried to boot it, same thing. Did not work. I was able to ssh into it and it said the it was missing something called Flask, I did not do anything to the software in any way that would make it stop working, please help.

Here is the error after updating:

Hello. Sorry for this inconvience, but in latest updates I added a lot of new features which requires additional libraries. You can install them using command:

sudo pip3 install -r requirements.txt

[Logan-Orr]

Do I reinstalled then do this, cause it gives me this error

[onlaj]

You need to be in visualizer directory

cd /home/Piano-LED-Visualizer/

[Logan-Orr]

Ok

[Logan-Orr]

[Logan-Orr]

Maybe I installed the wrong version?

[Logan-Orr]

Should I try to restart?

[onlaj]

What did it show after sudo pip3 install -r requirements.txt?

[Logan-Orr]

It installed everything, no error

[Logan-Orr]

Including flask

[onlaj]

Try to restart then, you can check installed packages with pip3 list

[Logan-Orr]

Like reintall and stuff Everythings there on the list, flask is 2.0.1

[onlaj]

For now just restart RPi, I doubt it will help but it's worth a try

[Logan-Orr]

K

[Logan-Orr]

Yeah did not work

[Logan-Orr]

Would this mean that it will not work for everyone else?

[onlaj]

Works for me, other users also tested latest update and no one reported problems with importing flask module.

I will soon make new release with everything configured.

[Logan-Orr]

Should I re download the image of the github page and use that have you updated the image recently

[onlaj]

No, image is not updated. btw. try to sudo pkill python3 before launching new script. When you ssh it autostart script, maybe you have moer scripts running and it can cause some problems.

[Logan-Orr]

Where am I supposed ptut this

[Logan-Orr]

You can just tell me the exact instructions or walkthrough of this like what commands to enter and when

[onlaj]

SSH to your RPi, then go into visualizer directory cd /home/Piano-LED-Visualizer/

stop all python scripts, just in case sudo pkill python3

start script sudo python3 /home/Piano-LED-Visualizer/visualizer.py

[Logan-Orr]

Did not work

[onlaj]

What does it show? Still the same error?

[Logan-Orr]

same error

[Logan-Orr]

I just installed a fresh software and its booted, and still on the old version, so no learn midi etc

[Logan-Orr]

what do I do now

[onlaj]

Well, I can only recommend that you reinstall everything (maybe try to follow manual setup?) or wait till I release new image.

I'd like to finish the webinterface first tho; hopefully, I'll be able to do it this week.

[Logan-Orr]

I GOT IT, what you have to do is run sudo pip3 install Flask before you update, and then right after you update, you have to install the requirements again before you reboot

[Logan-Orr]

oh and the web interface is cool! Keep working on it
