Re: Python 3.x as standard

I would like to see a bitter GUI maker than tkinker, I am trying wxpython but am having installation problem on the RPi, but the output in the docs. looks professional. I started using Python only about a year ago and very quickly abandoned Tkinter and wxPython. I like PyQt best for writing cross p...

Re: Python 3.x as standard

We are now way off topic but I must say that the discussion is interesting. I dislike the use of the word toy because it has no real meaning. A lot of people who read this are not native English speakers. Python 3 is a very powerful language with a huge amount of import possibility (pypi) I would li...

Re: Python 3.x as standard

Well, I bet your statement will not find very much resonance. Well I agree with Heater. C has been around for 45 years. It has changed a lot over that time and been used for more than half the software in the world. At no time has there been anything comparable to the Python2/Python3 debacle. Perso...

Re: Python 3.x as standard

Is it possible to make Python 3.x the standard python version? At the moment is set to python 2.7 is rather an old hat. Not a good idea as other scripts in your system may require Python 2. For Python 3 scripts use: python3 /path/script.py Or as mentioned make sure you have a proper 'shebang' as fi...

Re: Python 3.x as standard

scruss, I guess it's a sign that it's a mature language. I take the opposite view. Certainly Python has been around for a good long time. But it's still a toy language. It has no formally recognized standard, like C, C++, Javascript, Fortran, COBOL, Algol etc. Does it even have a formal specificati...

Re: Raspberry doesnt respond during openCV instalation

I had that when I compiled on a RPI3 using the number of CPUs option -J2, I changed to -J1 and the run was successfull.
One could also temporarily increase the swap space and leave the -j2. That works as well.

Re: Hardware Specification of the RPi's

Recomended power supply is 5v 2.5A at the board. The official power supply is actually 5.1v to compensate for voltage drop over the supply cable. If in doubt, buy the reasonably priced official power supply. It's always worth noting that we have sold MILLIONS of devices in to commercial or industri...

Well, the question has been answered: No Spec from RPi but some by other people. I don't believe that is the case at all. Perhaps you could detail a necessary specification which has not been officially provided? I had done that by providing an example in a previous comment. Or take a look at other...

Re: A Case for RPi

The case looks like it is to be used with a Pi emulating a Nintendo device. I would look for a more generic case for a consumer/commercial project that I would be selling. Possibly one that I could add my own branding to. You are probably right, but actually, the case looks great. There is an opena...

I've decided to completely re-install but this time use the opencv3.3.1 instead of the 3.4.1 on my RPi3.

So I think we close this now, thanking you for your assistance
