pymakr does not start

[robert-hh]

Hi abilio, I did a similar thing with Ubuntu 16.04, which I had installed a few days ago in a virtual machine, and there it works! So the set-up in my debian machine seems to be twisted. I see both Qt4 and Qt5 files, and that may be the source of the trouble. I cannot remove qt5 with pipx uninstall or atp-get remove.

Still, like the Windows version, pymakr does not convince me at all. It still seems not support wireless links to the boards, which is a shame, since the outstanding feature of all your products is their wirelesl support.
And for just another editor I see no need. At least, you should keep the options to configure and install your boards with command line tools, and document these properly.

Regards, Robert

It's using pyqt5 but pyqt4 is also there.
So yes, both versions are installed simultaneously.

[abilio]

@wathoom, I do believe that's the reason. In order to reproduce it, I'm going to install PyQt5 as well. I'll post back the findings.

[abilio]

@robert-hh, there was an issue with Pymakr beta 5 not syncing to the last WiPy 2/LoPy boards, but it has been fixed on beta 6. And for connecting over wireless, the support has always been there. You just need to type down the board IP number in the device field of the settings.

You could agree that editors are an issue of personal taste, and the most experienced users will have their favorite one. What we're trying to create with Pymakr is a tool for those Python newcomers and other users that like the simplicity of connecting to their boards without having to open a command line dialog and a FTP client tool. But rest assured we will try to maintain and improve the already existing methods as well.

Regards,

[robert-hh]

OK. Using the IP address does something: It tries to connect to my WiPy 1, but fails. My LoPy device is still on the road, since Oct. 12. It got lost somewhere on the mail. Isabelle tries to locate it..
And to be honest: the field tells: IP address or device. Is it possible to use an symbolic IP address?

[abilio]

Hi @wathoom, I can now confirm that having both PyQt4 and PyQt5 seems to be the culprit.

As we now identified the real cause of it, we will look for a solution to this problem and try to include it in the upcoming release.

Thank you so much for all your support and your patience.

[abilio]

@robert-hh . Yes, it is possible to put a name in that field, if you have a DNS (or hosts) entry for it. Can I ask something about your WiPy 1 setup? Are you running it as an access point mode=WLAN.AP , or station mode=WLAN.STA?

[robert-hh]

WiPy is running in it's default configuration as an Access point, and I can Telnet & ftp to it.

[robert-hh]

OK. I removed PyQt5 the hard way, and now pymakr runs. At least that's a second confirmation. I do not know the side effectes of that yet, but I might find it.

[abilio]

@robert-hh, thanks a lot for performing that test. It seems to me it definitely proves it.

Now about the WiPy failing, with your permission, I would like to go step by step on finding out the reason. Can I ask you to create a new thread for that specific subject, so future users can find it under the right label? Actually I created a completely separated category for Pymakr, it will be good for it to go there.

Thanks again for the test,
Abilio

This may be an issue with PyQt5's API. In PyQt 5.7, QLabel is not in module QTGui but in QtWidgets.

I tried the following patch:

diff --git a/modules/UI/SplashScreen.py b/modules/UI/SplashScreen.py

The same errors happen on pymakr_1.0.0.b6-1 under ubuntu yakkety. Just wanted to start. Any way to use command line tools and not pymakr? I have quite some experience with micropython, so what do I need to know to continue?

You can always use telnet for the REPL prompt, ftp for file transfer using your favorite tool and your favorite editor. With ubuntu, you can also mount the file system directly in the file manager (go to server) and edit the files in place, if you like. In my view, that works anyhow much better then pymakr with it's very-hard-to-view design.
All these 'nice' tools seem just a wast of effort, trying to replace stuff which already exists in better quality and broader selection.

[Ralph]

Hi @kephasp and @ulno,
At this moment, Pymakr is compatible with PyQt5 but doesn't handle PyQt5 very well. If you already had PyQt5 installed, it'll try to use it anyway. It's very high on our priority list to fix, but for the moment you'll have to uninstall PyQt5. I hope that's not too inconvenient in your cases.

[kephasp]

In my case, removing PyQt5 means removing Calibre. Not really an option.

In the meantime, changing the Debian package to accurately reflect this incompatibility would at least make it obvious what prevents it from working and prevent installing in a non-working environment.

[robert-hh]

Oh yes, that#s true. Calibre does not work any more. And since Calibre seems to be stable and I see pymakr still in an early alpha phase, I removed pymakr. It is anyhow not needed, since all the standard tools work and are reliable. If pycom's resources are limited, they should more focus on there boards firmware and not waste time on components, where a lot of alternatives exist for all operating systems.
Standard tools
Console: telnet, Screen, picocom, putty, Teraterm, ....
Filetransfer: ftp, filezilla, fireftp, linux file managers like nautilus, thunar, ...,
Code editor: Any editor of your choice. On linux, once you mounted the WiPy/LoPy#s file system in nautilus, you can directly edit the files on the module.

[kephasp]

We use Pycom or Arduino in a teaching context, where the UI component are rather critical.

Not really an option either to teach programming beginners that struggle with writing a 3-line function to use ftp and telnet

[robert-hh]

That's a point, but then pymakr should work reliably, like the Arduino UI does, as long as you stick with standard boards. At least, I never had any issues with installing Arduino on Linux or Windows.
AFAIK, the Windows version of pymakr has no installation problems, but I just tried an early version for a few moments.
