When ask Spyder to run my program from the Python Console it gives me different responses. Sometimes, it doesn't run the program, other times it hangs. When it hangs I have to manual break the program with Ctrl+enter.
Have I loaded Spyder incorrectly? Do I need to configure my interface differently? Any suggestions?
(Spyder developer here) Because of this and several other bugs, the Python console is going to be removed in Spyder 3.2.
Please use the IPython console instead.

I am using openpyxl in spyder IDE to create a new excel workbook. The program runs with no error, however no excel workbook was created.
I copied the code into sublime text, and ran the code in command prompt and it worked perfectly good, with the new excel created
Can someone please explain what i am doing wrong in spyder and how to fix it?
I got stuck with the same problem. To resolve it I verified the Python interpreter's version used by my Spyder (there were some of them on my computer). I found out that it wasn't using the one I needed it to. So I changed it to the appropriate version's one with the followed installation of the lacking Spyder kernels with python -m pip install spyder-kernels and all the specific modules I needed to complete my tasks.
Hope the advise to be useful. Have a nice day.
I have been running simple programs with python3.4 without trouble, directly typing the program name (without the .py extension) from a command shell, in the directory where the python scripts are located. The expected output would then appear in the shell, and upon termination of the program the next prompt appears, as expected. I recently upgraded to 3.6.4 to develop more complex applications using NumPy and pandas. since the upgrade however, running the same programs still work (e.g., I can see the tk windows appear and behave as before), but the next prompt immediately appear in the command window while the program is still running, and the expected output from simple print statements is redirected somewhere (where?). On another hand, running the program by typing 'python program_name.py' rather than just 'program_name' works as before, with the output appearing in the command window as expected. what configuration settings could have been present with 3.4.0 and missing with 3.6.4 that would explain those discrepancies? Thank you.
I am trying to use some libraries I downloaded, but whenever I check for them in IDLE I don't see them.
The same thing happens when I type from sklearn import datasets
But when I try to pip install I see this:
Does this mean I am limited to only the Spyder IDE?
There are somehow distinct distributions of Python that you seem to be running. I would suggest using virtualenv and running your IDE (idle/others) via that. Here's a tutorial video for it. [1]

I keep getting the same type of error messages and I have really done all I can to get rid of them. The message is as follows, only the module can vary at times:
ruby 5740 child_info_fork::abort: address space needed by 'date_core.so' (0x600000) is already occupied
These messages occur at various times when trying to run Rails, such as “rails console”.
I am running the following environment:
Windows 7 Ultimate 64-bit
Cygwin Net using setup 2.774 (installed from Internet mirrors)
Ruby 1.9.3p392
Rails 3.2.11
I have taken the following steps attempting to fix this:
Deleted all BLODA and restarted, including Norton 360 and Malwarebytes. (BLODA is Big List of Dodgy Apps.)
Deleted and reinstalled Cygwin.
Executed “rvm implode” and rebuilt the RVM and Ruby on Rails environment.
Used CMD & ASH to run “peflagsall” & “rebaseall”. Ran “rubyrebase”. Restarted.
Used FIND to build a file of all *.so & *.dll files. Ran “rebase -T”. Restarted. This has also been done using the “-b 0x77000000” switch.
Used same file to create “to_peflags” script issuing peflags against each individual file. Restarted.
All repair attempts have been futile. At times, “rebase -si |grep ‘*’” would be clean. Any attempt to run “rails console” or similar commands results in Address Space Occupied messages. Subsequent “rebase -si” would then again show conflicts.
I have been trying to run “peflags” against the Ruby modules, but I only get “skipped because could not open” error messages there. File permissions and ACL both show correct permissions. The same error occurs whether or not Administrator is used.
This is pretty frustrating. I would like to fix my current environment, but I am considering moving to MSYS or SFU, but I don’t know if either of those are decent options. I am also considering going native UNIX, but I’ll leap off the cliff when I get to it.
For now, does anyone have a fix for this specific error for me? Thanks…
I have used procexp to monitor "rails console" execution. Bash is calling cmd.exe to run the rails.bat file. Cmd.exe runs in ASLR mode. Used Microsoft EMET 3.0 to turn off mandatory ASLR and bottom up ASLR for both bash and cmd. Cmd.exe still runs in ASLR mode. It must be compiled that way.
Updated registry to set HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management\MoveImages to 0, -1 then 1. 0 caused system problems. -1 had no effect. 1, which was supposed to be the default, helped somewhat as long as EMET changes were in place. But, it was unreliable as Address Space Occupied would eventually recur.
Decided to attempt to install a command processor that either didn’t require ASLR or allowed me to disable it using PE flags. I installed TCC/LE and attempted to get Cygwin Bash to use it to process .bat files. I tried using the path variable, the COMSPEC variable and changes to batfile and cmdfile in the registry all to no effect. Cygwin Bash must either have it hard coded or some nonobvious control.
My fix is to replace my environment. I know I will eventually migrate to some Unix, but for now I am converting to MinGW/MSYS and RubyStack. All I want to do is to get a stable RoR (Ruby on Rails) environment running for today. I don’t see that happening using Cygwin with Windows 7 Ultimate. I keep running into too many problems and this one is a very, very tough nut to crack. Thanks…
I'm just getting started with erlide, using a fresh install of Eclipse Juno and erlide. I've used erlang on my system (64-bit Fedora) from the command-line, so I'm just trying to make the switch. I started with R15B, and have upgraded to R15B02 (built from source) as suggested by another SO post. If I right-click on a .erl file and pick Run As..Erlang Application, the IDE freezes and I have to kill it. If I try to run from Run Configurations and specify the module and function, it will start to execute, but never progresses beyond 27%. This is on a simple function that runs instantaneously on the command line.
Please try with the latest nightly from http://erlide.org/update_nightly, we did some work about similar issues, I hope they will solve yours too.
It would help to see the log from /erlide.log.
You can also open the launch configuration from run->configurations and see if there is some weird value in any of the fields in the "runtime" tab, most probably the node host name.
[I will be away for a week or so, so I can't answer very soon. Sorry about that.]
