I am new to python. I generated a macro which is a .py script using Abaqus Macro manager. I realised that this script works only when run from the Abaqus manager and does not run by itself.
Please does anyone know how to modify this script so i can run it without using the Abaqus. Thank you in advance for your help
Adroit
to run a python script that relies on abaqus cae from the command line and without opening up the gui window you do:
abaqus cae noGUI=script.py
As mentioned if all the script does is define a macro, well that's all it does is define the macro and quit. Typically you need to add code to open an odb, do something, write output, etc.
In general, Python scripts can be run in Abaqus via 'File > Run script'. However, as is a case for all Python scripts, if all your code is contained inside of a function (and in case of Abaqus macro, it is), and that function is never called explicitly inside the script, the code will not be executed.
You file probably looks something like this:
from abaqus import *
# some other imports, if any
def macro_function():
# code defining the macro's behavior
You should edit the script by calling the function at the end of the script.
If you want some more concrete help, post your actual code.
EDIT: To call the defined function, you just write macro_function() at the end of the file, so that the script looks something like this:
from abaqus import *
# some other imports, if any
def macro_function():
# code defining the macro's behavior
macro_function()
Maybe it would be easier if you just had the code outside of the function and remove the function completely. For anything more than this, you really should learn some Python.
According to my moderate experience, if you need loop computations, you have to launch the script inside CAE, since when starting it in command line, only one cycle is computed. An example of the script intended for loop computations and visualisation, you can find at researchgate, search text "How to write scripts for Abaqus"

I wounder what is the most efficient way to run a program, given as executable, from Matlab many times in a for loop. At the moment I use the following Code:
for i = 1:100
system('MyProgram.exe');
% Do something with the output from the .exe
end
So, from the profiler I know that 99,9% of the time is used in the execution of the Program itself. My question is basically if there is a more efficient way to run executables in general from within Matlab?
I have read that everytime I run an exe like described above, a process is created which has to initialize the Matlab runtime environment... Is there possibly a way to avoid this by only doing the initialization once and from there on run the programm multiple times?
I am guessing your can't directly modify the .exe's you are given, so perhaps there is a way to instead of calling the .exe directly, you could call a .bash shell script.
I would imagine that if you do this and within the shell script check to see if a workspace is already open to associate the execution of the .exe with a specific process ID. Although I would guess that when the executable finishes it closes the session.
Just throwing some stuff out there :P I have had lots of trouble with how Matlab handles this kind of thing (Also things like Excel).
Hope you figure this out.
EDIT: I found some possible examples here Example Descriptions

Before you answer, I'm not looking for the functionality of ; to suppress command line printing.
I have a set of scripts which are not mine and I do not have the ability to change. However, in my scripts I make a call to these other scripts through evalin('base', 'scriptName'). Unfortunately, these other scripts do a lot of unnecessary and ugly printing to the command window that I don't want to see. Without being able to edit these other scripts, I would like a way to suppress output to the command line for the time that these other scripts are executing.
One potential answer was to use evalc, but when I try evalc(evalin('base', 'scriptName')) MATLAB throws an error complaining that it cannot execute a script as a function. I'm hoping there's something like the ability to disable command window printing or else redirecting all output to some null file much like /dev/null in unix.
I think you just need to turn the argument in your evalc example into a string:
evalc('evalin(''base'', ''scriptName'')');
Have you tried this solution
here ?
echo off;
I don't know if it will fit your needs, but another solution can be to open a new session of Matlab, and use there only minimized -nodesktop form (-just the command window). You can run from there the annoying scripts, and work on the main session as usual.
The problem here is that the sessions can't be synchronized, so if you need to work with the results of the scripts all the time, it'll be a little bit complicated. Maybe you can save the result to disk, than call it from the main session...
But it mainly depends on your workflow with those scripts.
So I'm writing Python with IDLE and my usual workflow is to have two windows (an editor and a console), and run my script with F5 to quickly test it.
My script has some non-optional command line parameters, and I have two conflicting desires:
If someone launches my script without passing any parameters, I'd like him to get an error telling him to do so (argparse does this well)
When I hit F5 in IDLE, I'd like to have my script run with dummy parameters (and I don't want to have more keystrokes than F5 to have this work, and I don't want to have a piece of code I have to remember to remove when I'm not debugging any more)
So far my solution has been that if I get no parameters, I look for a params.debug file (that's not under source control), and if so, take that as default params, but it's a bit ugly... so would there be a cleaner, more "standard" solution to this? Do other IDEs offer easier ways of doing this?
Other solutions I can think of: environment variables, having a separate "launcher" script that's the one taking the "official" parameters.
(I'm likely to try out another IDE anyway)
With some editors you can define the 'execute' command,
For example with Geany, for Python files, F5 is python2.7 %f. That could be modified to something like python2.7 %f dummy parameters. But I use an attached terminal window and its line history more than F5 like commands.
I'm an Ipython user, so don't remember much about the IDLE configuration. In Ipython I usually use the %run magic, which is more like invoking the script from a shell than from an IDE. Ipython also has a better previous line history than the shell.
For larger scripts I like to put the guts of the code (classes, functions) in one file, and test code in the if __name__ block. The user interface is in another file that imports this core module.
Thanks for your question. I also searched for a way to do this. I found that Spyder which is the IDE I use has an option under Run/Configure to enter the command line parameters for running the program. You can even configure different ones for the different editors you have open.
Python tracker issue 5680 is a proposal to add to Idle a way to set command lines args for F5 Run module. You are free to test any of the proposed patches if you are able to apply them.
In the meanwhile conditionally extending sys.argv as done below should fulfill your requirements.
import sys
in __name__ == '__main__':
if 'idlelib.PyShell' in sys.modules:
sys.argv.extend(('a', '-2')) # add your argments here.
print(sys.argv) # in use, parse sys.argv after extending it
# ['C:\\Programs\\python34\\tem.py', 'a', '-2']
Is there a way for "ipython3 notebook" to receive command line arguments with its 'run' button?
Thank you very much.
I just encountered this problem when I tried to run some scripts using argparse library in Jupyter Notebook. Since I don't want to do much modification to the code, I needed to provide sys.argv[] to the parser.
In my case, such code can solve the problem:
import sys
sys.argv=['self.py','arg1','arg2']
Because in a real command line, the first element of sys.argv is the name of the script, so you have to provide a random script name or a name that suitable for your application, and the following arguments are just like they are passed by a real command line.
This works for me so far, but I don't know if it is safe and elegant, wish this could help you.
Do you mean the Cell -> Run menu item? If so, no. The notebook's not really designed to be used like that. What are you trying to do?
I'm a Perl programmer doing some web application testing using Selenium. I was wondering if there's some kind of interactive interpreter which would allow me to type Selenium commands at a prompt and have them sent to selenium.
The way I'm currently developing code is to type all of the commands into a Perl script, and then execute the script. This make the development process painfully slow, because it makes it necessary to rerun the entire script whenever I make a change.
(If I were a Ruby programmer, I bet the Interactive Ruby Shell could help with this, but I'm hoping to find a solution for Perl.) Thanks!
The Java-based SeleniumServer has an --interactive mode.
I don't know about a Selenium shell, but if you are looking for a Perl REPL, there are modules such as Devel::REPL and Carp::REPL. I've made shells for various simple things using my Polyglot module, although I haven't looked at that in awhile.
May I ask why it's "necessary to re-run the entire script"? Since your solution is an interactive shell, i'm assuming that it's NOT because you need previous commands to set something up. If that's a correct assumption, simply make your set of Selenium commands in Perl script in such a way that you can skip the first N commands.
You can do it by explicit "if" wrappers.
Or you can have a generic "call a Selenium command based on a config hash" driver executed in a loop, and adding the config hash for every single Selenum command to an array of hashes.
Then you can either have an input parameter to the test script that refers to a # in an array; or you can even include unique labels for each test as a part of a config hash and pass "start with test named X" or even "only do test named X" as input on command line.
