I'm trying to use the Matlab Engine API for Python and I installed using standard procedure on Matlab's site.
However, it takes forever and doesn't show any prompts.
Until I manually break and exit.
Any installation issues that I'm missing here?
I don't get an error message either.
The "unknown error" that is displayed is after I provide a keyboard interrupt.

I am a beginner in Twincat and is trying to run a sample program on my system(not on target).
I did all the steps mentioned here and did get the system up and running my sample code once. However, when I tried to run it again after a system restart, I get an error message.
I tried creating a new empty solution and another one with test code, both of them throws the same error code. Also, when I click on the green Restart TwinCat system button, I get the following error.
How do I solve this?
You need to enable AMD-V in your BIOS.
The procedure is explained here:
https://youtu.be/P9uUgT8EhUM?t=1029
(This is done for an Intel system, while you seem to have an AMD system, but it's the same procedure).
Also make sure to run this file in CMD (as Administrator):
C:\TwinCAT\3.1\System\win8settick.bat
And then reboot your computer.
If this doesn't do the trick, then do core isolation and run your TwinCAT task on an isolated core. Maybe that was what you were doing before but not now? It's described quite well in this video: https://youtube.com/watch?v=q7iRvDuAOFQ
We have a custom installer which installs several components, along with that, it executes series of SQL commands for PostgreSQL 9.5 database. At one of the systems, following error was generated (this was shown in a pop-up box having title: Microsoft Visual C++ Runtime Library)
Runtime Error!
Program: <PostgreSQL install path>\bin\psql.exe
R6016
-not enough space for thread data.
Once the button 'Ok' was clicked, the installation went ahead and was successful. The software appears to work just fine after the installation. I read about this issue at links: link1, link2, link3. But could not determine whether that error caused any damage etc.
Since the thread (or may be several threads) initiated by psql.exe got aborted, certain operation(s) (performed by those threads) must not have completed. If that is the case, then it might be a serious issue.
Any idea, what should be done in this scenario? How to verify whether that error affected anything or not?
I am not sure if this info helps, but my GUI tool has text boxes for user input, push buttons, drop downs, and an axes to show histogram plot.
The deployment machine is a Windows 7 64 bit. The MCR is installed without any issues (using mcr file packaged with the GUI). The GUI opens in deployed machine. However it does not function properly. Just gives beep sound when using any functionality like pressing a button, no error messages are shown.
I ran the exe file through the dependency walker, and it shows the following errors:
API-MS-WIN-APPMODEL-RUNTIME-L1-1-0.DLL
API-MS-WIN-CORE-WINRT-ERROR-L1-1-0.DLL
API-MS-WIN-CORE-WINRT-L1-1-0.DLL
API-MS-WIN-CORE-WINRT-ROBUFFER-L1-1-0.DLL
API-MS-WIN-CORE-WINRT-STRING-L1-1-0.DLL
API-MS-WIN-SHCORE-SCALING-L1-1-1.DLL
DCOMP.DLL
IESHIMS.DLL
LAUNCHERMAIN.DLL
(Error opening file. System cannot find the file specified) for all the above.
Run the executable from a dos window in order to obtain all messages that normally would write to matlab console ...
I'm suspecting that some matlab routines used in your buttons were not embedded during compilation (and the beep corresponding to "warning, error in gui callback function "lalala" is undefined).
NB: I don't think there is any issue for missing dll in dependency walker ... else your exe would not run at all and would wrote "Failed to load module".
You are likely missing the Visual Studio redistributable package. Download and install it on the deployed machine.
Previously I have been using a python environment maintained by Mac ports. I had some basic scripts using PyQT, VTK, matplotlib etc. I have been able to use Paraview but seem a little heavy for my uses so I though I would try MayaVi2 (and TVTK).
I downloaded and tried to manually installing but it proved troublesome. So thought I would bite the bullet and try Canopy (academic License). Based on this VTK/Mayavi on Mac OS X which suggests all is good in the world of Qt, VTK and MayaVI, I installed 64 bit Canopy.
I am having trouble getting mayavi2 to work within the Canopy environment. It runs, but the console gets lots of errors, if I call up any dialog/setting box the "buttons" don't work properly. Here is the first error (of a couple of screen fulls) when I try to start mayavi2:
(Canopy 64bit) scratch_pad 501 $mayavi2 Traceback (most recent call
last): File
"/Applications/Canopy.app/appdata/canopy-1.0.0.1160.macosx-x86_64/Canopy.app/Contents/lib/python2.7/site-packages/pyface/ui/wx/splash_screen.py",
line 121, in _on_paint
dc = wx.PaintDC(window)
I am actually more interested in TVTK, so I tried some of the mayavi demos from the website gallery http://docs.enthought.com/mayavi/mayavi/auto/examples.html The few I tried kind-a worked, that is they display a VTK (?) window/scene, I can interact with the VTK window. All is good until I open a settings/dialogue window, and then none of dialogue window "button" work and i have to force quit. Here is the last line of error when I open the "Setting" button in the plot3D demo:
simple demo: File
"/Users/michael/Library/Enthought/Canopy_64bit/System/lib/python2.7/site-packages/wx/_core.py",
line 9162, in DestroyChildren
return core.Window_DestroyChildren(*args, **kwargs) wx._core.PyAssertionError: C++ assertion "GetEventHandler() == this"
failed at /BUILD/wxPython-src-2.9.2.4/src/common/wincmn.cpp(468) in
~wxWindowBase(): any pushed event handlers must have been removed
I even tried
ipython --gui=wx
(as suggested on the page) but in this case it crashes, no window.
Based on the error messages on the console they all appear to be wx related. It is my understanding the the Canopy environment is "self-contained", but could my old environment be somehow conflicting? How would I even test this?
Is there a way, environment variable, that mayavi2 can use Qt instead of wx? I don't use wx in any of my local python scripts, so unless it is needed in Canopy I am quite happy to disable, if that is an option.
Any ideas?
After running most of the examples in the Mayavi Gallery I have discovered that I needed to inform Traits to use Qt. This was done by setting an environment variable from within the script using a sys.environment() call. I decided to set the environment variable ETS_TOOLKIT to qt4 in my .profile as follows:**
export ETS_TOOLKIT=qt4
Mayavi2 now works as advertised!
I am using Microsoft Robotics Studio for a school project and I am getting a strange error when I try to run the Visual Simulation Environment. It was working fine until yesterday and then suddenly it gave me a runtime error saying "Illegal command line arguments... do not use VPLHost directly, use dsshost instead to run a manifest" But I am only clicking on Run in VPL/DSS Manifest editor.
I am running MRDS as administrator and I even tried re-installing MRDS but it is still showing the same MS VPL Runtime error. I tried to search online, but cannot find any suitable solution.
I already tried running the existing samples, I.e. Urban Environment, Multiple Simulated Robots etc. but it still gives me the same error. The strange thing is that it was working perfectly one minute, and then started giving me this error message the next minute, when I had not changed anything in between. In fact, I had wanted to change something in my manifest, so I closed the running VPL application, closed VPL and opened DSS manifest editor, and ran my manifest and that is when I got this error.
What is going wrong? Is some MRDS script using vplhost32.exe instead of dsshost? If so, then where and how do I change it?
I tried running the urban envrionment manifest from the command prompt and Using DSSHost32 directly. This time, it didn't give me a runtime error but an intiialization error. I tried changing port numbers but it still doesn't work. I have deleted many files from my computer to free space (JIC) and it still doesn't work. The window just doesn't open even when I hover over it in Windows 7.
The error message looks like this: Only one usage of each socket address (protocol/network address/port) is normally permitted."
This was even after I checked netstat for free ports and tried but I get this error message. Its either this one or the "Don't use VPLHost directly" if I run it through VPL or DSS Manifest Editor.
Could it be that some external services are interfering with DSSHost/VPLHost? Are there any such services which I could try killing? ANY help/suggestion would help right now as my project is due Thursday and this is a really unfortunate time for it to be acting up like this.
Does the problem reproduce after logging off & logging back on? It's likely that you had a process hanging around that you weren't aware of. Logging off should shut down any processes you personally started.
I don't know the solution of your problem, but it would be better that you post your question on the link below:
