I have a python 2.7 anaconda environment (I can't upgrade it to python 3 yet, I hope python2 isn't suddenly viewed a security threat). This python was working fine last week. This morning I come in and try to run some python code in it (that I haven't run before, but came from a contractor of ours).
When I ran it I noticed that (I don't think it was a coincidence) Windows suddenly reported a threat:
and now when I run python, I get:
$ python
bash: /home/username/anaconda3/envs/my_env/bin/python: cannot execute binary file: Exec format error
and when I try to disable the quarantine from Windows Security, I still get that same error.
I'm using Ubuntu Windows Subsystem Linux. I've never seen an error like this before.
Does anybody know what might be causing this problem (or how to recover without rebuilding my environment, assuming that would work)?
Update: I deleted that environment, upgraded Anaconda, and rebuilt my environment (python 2.7) from scratch. It appears to be working again, including what I'd tried before that might have triggered the problem.
I also noticed that my "Virus & threat protection updates" had updated itself 30 minutes before this problem started (at 8:23), and it has since updated again (at 9:45). So perhaps some errant security definition?
Support for Python 2.* ended starting with 2020 (EOL)
I'm quite new to Python (Got forced to use it since BBG don't support R), and i'm having difficulty installing blpapi. I'm currently using Spyder and Python 2.7 version.
Does anyone on this forum had already used python to send orders to Bloomberg and manipulate data provided by the terminal? If Positive, could you pls share how you've installed the API Libs and any other useful stuff. The idea is to feed a certain model with live data.
There's an .exe file in the Zip that you download from WAPI , but there's an error message appearing. I've already tried to speak with a BBG represent. but that does not helped.
Regards,
I have encountered this issue and tried all previous solutions to no avail. Have tried rolling back requests to older versions, have tried updating pyinstaller. Please guys, if you know a configuration that works, let me know.
I am compiling some python 2.7 code that uses Kivy
I am an idiot. I was piping the wrong python install. I use a separate version for other projects, and I sandbox my kivy one to prevent conflicts... too bad I forgot about that :)
I saw there was a previous question about installing PyQt on a Mac, but unfortunately I'm not quite able to comment on the thread so I had to post a new question. Like that user, I have been having issues downloading QT 4.11.1. I downloaded SIP as well as PyQT4 (link to instructions), but when I try to run python configure-ng.py from my downloads folder, I keep getting the same error saying:
Error: Use the --qmake argument to explicitly specify a working Qt qmake.
Unfortunately I can't find the Qt settings which means I can't keep following the directions from the previous answer and I was hoping someone might be able to help walk me through how to download this module. Sorry for the duplication and thanks in advance.
Resolved April 15, 2013.
In windows 7 (64bit) windows explorer when I right clicked a Python file and selected "edit with IDLE" the editor opens properly but when I run (or f5) the Python 3.3.1 program, it fails with the "IDLE's subprocess didn't make connection. Either IDLE can't start a subprocess or personal firewall software is blocking the connection." error message. All other methods of starting IDLE for running my python 3.3.1 programs worked perfectly.
Even the "Send to" method worked but it was unacceptably clunky. I've spend four days (so far) researching this and trying various things including reinstalling Python many times.
And NO it's not the FireWall blocking it. I've tried totally turning Firewall off and it had no effect.
Here's an important clue: In the beginning I installed and configured python 3.3 64 bit and everything worked including running from "edit with IDLE" but then recently when I needed a library only available in Python 2 I installed python 2.7.4 and from that point on the stated problem began. At one point I completely removed all traces of both versions and reinstalled Python 3.3.1 64 bit. Problem remained.
Then I tried have both 32 bit versions installed but still no luck. Then at some point in my muddling around I lost the option to "edit with IDLE" and spent a day trying everything including editing in Regedit. No luck there either. I reinstalled Python 3.3.1 still no "edit with IDLE" then Finally I uninstalled all versions of Python and I removed python references to environment variables PATH and PYTHONPATH. Then I Deleted all the Python related keys in the windows registry, deleted the C:\python33 directory that the uninstall didn't bother to delete. Overkill, of course, then I restarted windows and installed Python 3.3.1 64 bit version again and thankfully the option to 'edit with IDLE' was back. I was momentarily happy, I opened windows explorer, right clicked on a python program, selected 'edit with IDLE' selected RUN (eyes closed) and you guessed it, same original error message "IDLE's subprocess didn't make connection. Either IDLE can't start a subprocess or personal firewall software is blocking the connection."
I am completely stuck on this issue and really need help. Pretty sure that you can see I and not a happy camper. And to top it all off, I guess I don't understand StackOverflow yet, I have had this plea for help up in various versions for 5 days and not one response from anyone. Believe me I've looked at every thing in stackoverflow plus other sites and I can't see the answer. Almost seems like I have to answer my own question and post it, trouble is, so far I can't.
Anyway, thanks for listening. Yes I'm pretty new to Python but I've been programming and overcoming problems for many years (too many perhaps). anyone? Not personally having someone that is familiar with Python makes this difficult, how can I get in touch with an expert in Python for a quick phone conversation?
I had this same problem today. I found another stack overflow post where someone had a tkinter.py file in the same directory as python, and they fixed it by removing that tkinter.py file. When I looked in my python directory, I realized I had created a script called random.py and put it there. I suspect that it conflicted with the normal random module in python. When I removed this file, python started working again.
So I would suggest you look in your main python directory and see if there are any .py files that you could move to different places.
I'm running Windows 7 64-bit. I saw the same errors today. I tracked down the cause for me, hopefully it'll help you. I had IDLE open in the background for days. Today I tried to run a script in IDLE, and got the "IDLE's subprocess didn't make connection. Either IDLE can't start a subprocess or personal firewall software is blocking the connection." errors. So I closed all IDLE windows, and tried to restart IDLE. That then caused the same errors to pop up, and now IDLE wouldn't open successfully.
The cause was an extra pythonw.exe process running in the background. If I open up an instance of IDLE, then open a second, the second has issues connecting, and closes. But it does not close the instances of pythonw.exe that it opened, one is left running in the background. That extra instance then prevents future attempts to open IDLE.
Opening up Task Manager and killing all pythonw.exe processes fixed IDLE, and now it functions properly on my machine (1 instance open at a time though!).
Look for files on your main python folder that you may create in names like "threading.py", "tkinter.py" and other names that overlapps with your Lib folder and move/delete them
Adding to existing answers - it is actually possible to have firewall block IDLE when not running with -n flag. I haven't used IDLE for a few months and decided to try if it works properly with newly installed python3.3 (on Linux Mint 13 x86). In between I made iptables setup much more aggressive and apparently it blocked idle-python3.3 from connecting to the Python RPC server. Sometimes it is just what the message says.
I had exactly the same issue :"IDLE's subprocess didn't make connection. Either IDLE can't start a subprocess or personal firewall software is blocking the connection."
I found the answer from this stackoverflow site. I created a file named string.py and that classhed with the normal python files. I removed the string.py and everything works now. Thanks folks.
I had the same error message. Error not seen after I added all the *.exe filea to be found in the Python install directory to the Windows firewall exception list.
I finally got it to work when I disabled ALL firewalls and antivirus, because some antivirus ALSO have firewall control. Ex. avast
Remove copy.py in your folder if you happen to have one
Using Windows 7 64 installation of Python 2.7.10 Shell I solved the above problem by opening the program as an administrator.
i have the Same issue on os win7 64Bit and Python 3.1 and find a workaround because i have a Project with many .py files and just one gave this error. - Workaround is to copy a working file and copy the contents from not working file to working file. (i used Another editor as idle. The Problem with that workaround is... of you rename the file it doenst work. attention just rename the not working file doesnt work for me. just that copy paste. – john
I came across this problem too. There are two things you can do
You may already have a process running call pythonw.exe which prevents IDLE from being starting. End that task and try running IDLE again
Use pythonwin or python command line
