Fail to Start Matlab on Windows.

[Rahuketu86]

I have Anaconda Python distribution installed on windows 10 64 bit. I installeed Zeromq, pymatbridge using pip.

While running following commands I get the error matlab failed to start :-

A matlab server pops up saying

To get started, type one of these: helpwin, helpdesk, or demo. For product information, visit www.mathworks.com.

Error using messenger Socket creation failed.

Error in matlabserver (line 7) messenger('init', socket_address);

»

Please advice how to resolve this.

I'm not sure. It does look like it's trying to do the right thing, but failing to connect with the messenger.

I have the same problem

Error using messenger
Socket creation failed.

Error in matlabserver (line 7)
messenger('init', socket_address);

I am on Windows and aware that Windows is not supported currently :) matlabserver tried to connect on tcp://127.0.0.1:61276 but failed really fast (below 1-2 seconds from calling mlab.start()). I thought I will try to dig into this - any pointers on how to proceed?

I am sorry to not be more responsive here. Offers to help -- I embrace with both hands. I think that this has to do with the parts of the code that need to be compiled (the "messenger"):

That part of the code lives here: https://github.com/arokem/python-matlab-bridge/tree/master/pymatbridge/messenger

And make.py is the driver for compilation on different platforms. We ship the compiled mex files together with the code in that directory (organized according to platform).

I will try compiling messenger then - but because I have never compiled anything before, this may take me some time :snail: . I saw the tips on compiling messenger here so I hope I won't get lost. :octopus:

I had the same problem on Windows 10. The problem is that Matlab cannot find the mex file messenger.mexw64.

It connects if you copy the mex file from pymatbridge\messenger\mexw64 to pymatbridge\matlab in your Python package folder.

I have the same error on Windows 7 x64, but with a bit more information:

??? Undefined function or method 'messenger' for input arguments of type 'char'.

The rest of my error message is the same as above. So indeed, there's a problem with the "messenger".

And indeed, as @quic0 suggested, copying messenger.mex and messenger.mex64 (I copied both just to make sure) allowed the bridge to connect to Matlab! Thank you @quic0 !

We should do something so that the messenger gets installed into that folder, I guess. Thanks for reporting.

When doing the following:

I'm still getting the following matlab pop up:

Error using messenger Socket creation failed.

Error in matlabserver (line 7) messenger('init', socket_address);

I'm using anaconda on a windows 7 and have installed pymatbridge. I also tried copying and pasting the mex file from pymatbridge\messenger\mex64 to pymatbridge\matlab but this didn't make a difference (the file was also already there). Any suggestions?

[arokem]

Sorry - I don't have access to a Windows machine, so I am limited in supporting work on that platform (and tbh, quite limited in supporting other platforms as well, just because this is not exactly a top priority for me at the moment). You might have better luck installing from source from this repository.

@shayqn you are not supposed to copy paste the .mex file;

From mexw64 folder, you are supposed to copy paste the 'messenger' file

@shayqn What I did was put the messenger and messenger.mex64 in the pymatbridge matlab folder, and I put them in the directory where my code was (say my ipynb file), and it worked!
