When I run Python portable, sometimes it crashes, sometimes it does not. I am not sure if it is clashing with another program or if it is something else. I can never reproduce this situation. Can anyone help?
First i would start it after a fresh reboot and look which services run directly after reboot and after first, second... programm start.
Then looking at the ram acn be intresting. Maybe you got a ram leak/overflow.
Then i would compare theese results with a program start, when you did ur typical stuff (office, games, internet, videos)
Do you maybe run the x86 version on a 64bit computer? Is your ram generally ok (memtest), on which core does it run for you (multicore processor), Wchich version do you run (is it the newest)?Do you get the same results on a different Computer?
Perhaps some of this helps, yours JungerIslaender

I'm lost with Python. After troubleshooting with a friend through Discord for literally months I am about to give up. This is my last attempt at trying to get Python fixed on my Windows 10 laptop.
I'm using a Lenovo Legion 5, bought the laptop in November 2020. I've not been able to get anything related to Python to run in the CMD window. I can run Python no problem, but nothing I have installed through pip has ever worked. I can use virtualenvs, but only through PyCharm for example. Python has never really worked through the command line.
Yes I tried reopening the CMD window, rebooted the system many times, ran the CMD as administrator, installed the path variables for both Python and esptool.py but nothing seems to help.
I honestly don't know where to start because none of the 250+ websites I've visited to so far that suggested a fix for any kind of issue I've been experiencing with Python has been working. I can run Python fine by the way, just none of the things installed through pip will work.
Let's start with a use-case:
I'm trying to run esptool.py so installed it with pip install esptool. This install worked fine, and I can confirm it is installed with pip show -f esptool.
However, when running esptool.py version it told me:
'esptool.py' is not recognized as an internal or external command, operable program or batch file.
So I added the local folder from the previous step to the %PATH% variables, after running esptool.py version it gave me a popup asking me with what kind of program I should open this, I didn't select to open with this kind of program from now on. This makes it so that I do not get an error, what now happens is that another window quickly opens and then exits without an error code. So I have no clue what's happening.
What should happen is that it should tell me which version is installed in the CMD window.
There have been a few other things going on with my Windows 10 install, for one, the username that I used during the installation wasn't used to create the user directory. Windows 10 somehow instead chose a name that was related to the first 5 characters of my email address, which is totally strange as I haven't used that string in the installation of Windows 10 at all. This was a fresh install on a new laptop.
Now, after an update of Win10 my user icon doesn't display anymore and I had to change ownership of the 'Windows Apps' folder in order to be able to access it. Changing the ownership also changed the name I now see on the login screen when I boot up the laptop. It changed from the 5 first chars of my email address to my full name in the login screen, only because I took ownership of this folder so I could access it.
There have been a lot of things going on that I think should not be changing all the time, things to do with administrator rights, ownership, etc.
Now, since opening esptool.py doesn't open it, but also doesn't show me an error, I'm clueless and the only thing I can think of is doing a fresh system install, but I have a bunch of projects going on for which I need this laptop in working order and I don't have the mental health (due to corona) left to do a fresh system install. I'm worn down. Not in a dramatic way, I just don't have the spare energy to go through the whole process. So I'm hoping someone can point me in the right way to troubleshoot why my Python doesn't want to work natively.
What happens when running esptool.py version is that I can see it opens a Python window, but without showing any content it closes within a few milliseconds.
What is going on, how do I continue? I hope someone knows how to troubleshoot my system, to find the core of the problem.
It apparently was rather simple. First of all, thanks for the replies! And second of all, thanks for pointing me to superuser.com I wasn't aware of the site and will continue there.
The fix was to use python -m pip install esptool as suggested by Valentin Kuhn.
To answer AKD, I have a lot of experience with programming on my MacBook, but I'm not experienced with actually maintaining the system side, I'm a creative user. It's just that ever since I got a Windows laptop it's been nothing but trouble and after months of chatting about each individual issue with people on Discord nobody has been able to find a solution. I'm not expecting a GUI, just a simple "esptool.py v3.0" was the answer I was expecting from the command line.
Now what I don't understand is that I've never found any hint to anyone suggesting python -m. I will get on superuser to find out more about why the standard instructions that work for most people, don't work for me.
Sorry for using the wrong site for my question, I came on here through another related question and it was past my bedtime and I wasn't thinking clear.
I run a complex python program that is computationally demanding.
While it is complex in terms of number of lines of code, the code itself is simple: it is not multi-thread, not multi-process and does not use any "external" library, with the exception of colorama, installed via pip.
The program does not require a big amount of memory.
When I run it, and monitor via "htop", it shows one (out of the eight) cpu is used 100% by the script, and around 1.16GB (out of 62.8GB) of memory are used (this number remains more or less steady).
After a while (10 to 20 minutes) of running the script, my ubuntu dell desktop running ubuntu 16.04 systematically freezes. I can move the mouse, but clicks do not work, the keyboard is unresponsive, and running programs (e.g. htop) freeze. I can only (hard) reboot. Note that the last frame displayed by htop does not show anything unexpected (e.g. no higher usage of memory).
I never experience such freezes when not running the python program.
I do nothing special in parallel of running the script, aside of browsing with firefox or dealing with mails using thunderbird (i.e. nothing that would use cpu or ram in a significative fashion).
I have printed traces in my python code: it never crashes at the same state.
I also print kernel logs in another terminal: nothing special is printed at the time of the freeze.
I do not use any IDE, and run the script directly from a terminal.
Searching for similar issue, it seems that they are usually related to overusage of memory, which does not seem to be my case.
I have no idea how to investigate this issue.
I just started trying out PyCharm, and while it is very nice, I found the interactive console in debugger (that can be activated with "Show Python Prompt" on a breakpoint) is unusably slow. If I keep pressing enter, for example, after 2-3 tries, I have to wait several seconds for the next prompt to show up.
Is this a common experience? I'm running Pycharm with a pretty fast machine (with i7-3770 CPU) so I was wondering if something is wrong.
I too have experienced the same problem quite a few times but With every new version released new problem too pop out . Its not the first time PyCharm is giving some one a hard time. In previous version the IDE would just stop working or not debug at all .
The best way to solve this is by writing to Jet Brains so they can find and solve the issue and release a new update.
I created an executeable of my Python script. Everything works just fine on my first computer but when I try to run this very same executeable in another computer, it wont work. When I try to run my executeable I see that computer tries to open it, because command prompt window appears but nothing else happens, prompt window will disappear. Problem can't be in computer, because both my computers are 32 bit Windows machines and I have done similar things before but this kind of error I see first time.
I don't want to post my code at first, because it is more than 500 lines long. But I will give some more specifications about my problem.
This program I create is actually advanced version of application i made earlier. And earlier version worked fine in both of my computers. This advanced version, I am working on now, is developed into many standalone Python scripts unlike first one which was only one script. Could this be the source of my problem? Should I do something different when running setup.py now when I have many scripts?
And then there is third version of my application. Executeable of it runs fine on computer where I created it, but in my second computer it wont run either. But this time I get error too. When I run this program in my second computer the opening screen of aplication appears, there are some buttons which are meant to open other scripts, when they are clicked on. But when I click them I get following error: The system cannot find the path specified.
If someone is willing to look into my long code, then I am willing to share it. But again I dont want to post it here.
I am using Python 2.7 and windows 7 in my first computer and windows XP on my second computer.
I would be very grateful if someone points me right direction which helps me to solve my problem.
I use IPython very frequently and happily. Somehow, cutting text from the shell using the keyboard shortcut, Ctrl + X, is broken. Actually, I have a few different installations of IPython. In some of the installations, the shortcut works; in the others, it doesn't work.
What might be the reason for this? Where should I look into?
You say you have multiple instances installed -- are these all on different machines? What operating system(s) are they running? If you access them remotely, what operating system are you running?
Do you get to them using ssh? Do you run something like screen, either locally or remotely, or both? There are lots of things that can interfere with your terminal settings, especially when you're working remotely.
I'm almost certain that iPython doesn't have anything to do with it -- though you might want to check the version numbers, to see if working and non-working environments are running different versions.
More likely, it is something in the terminal emulation layer, but you'll likely have to do some detective work of your own to find out what piece is causing it.
Take it one step at a time -- try to cut from a local shell, to make sure that works. Then connect to a remote machine, and cut from that shell. Start screen, if that's your normal way of doing things, and test from that shell. Then start ipython. If it stops there, then see if you can find another application on the same machine that's linked against gnu readline, and try that. You may find that none of the console apps cut proplerly on that machine, or you may find that they work, but not under screen. Or you may find that something in the terminal settings stops everything from working as soon as you ssh in.
You may also have some luck. if you can find out what terminal the remote machine thinks you are using ( echo $TERM ) by copying the termcap file from a working machine to one that doesn't. That's a bit more involved for these forums, though -- I'd repost at that point on serverfault.com or superuser.com
I hope that at least gives you a starting place -- terminals are finicky, and difficult to get right. Most people seem to not bother, as long as everything mostly works.
