Error in building MATLAB wrapper: No module named 'gtwrap' #1118

SarveshS325 · 2022-02-22T09:13:19Z

Description

I am trying to build the MATLAB wrapper. Getting the following error

Traceback (most recent call last):
  File "/home/sarvesh/Libraries/gtsam/wrap/scripts/matlab_wrap.py", line 11, in <module>
    from gtwrap.matlab_wrapper import MatlabWrapper
ModuleNotFoundError: No module named 'gtwrap'
matlab/CMakeFiles/gtsam_matlab_wrapper.dir/build.make:86: recipe for target 'wrap/gtsam/gtsam_wrapper.cpp' failed
make[2]: *** [wrap/gtsam/gtsam_wrapper.cpp] Error 1

make[1]: *** [matlab/CMakeFiles/gtsam_matlab_wrapper.dir/all] Error 2
Makefile:165: recipe for target 'all' failed
make: *** [all] Error 2

Steps to reproduce

cmake -DCMAKE_BUILD_TYPE=Release -DGTSAM_TOOLBOX_INSTALL_PATH:PATH=$HOME/matlab/toolbox  -DGTSAM_BUILD_UNSTABLE:OPTION=ON  -DGTSAM_INSTALL_MATLAB_TOOLBOX=ON ..

make

Environment

Ubuntu 18.04
gtsam 4.1.1
MATLAB 2018a
Python 3.8.12 (conda env)

Additional information

I am able to build the python wrapper just fine

cmake -DCMAKE_BUILD_TYPE=Release -DGTSAM_BUILD_UNSTABLE:OPTION=ON -DGTSAM_PYTHON_VERSION=3.8.12 -DGTSAM_BUILD_PYTHON=1 ..

The text was updated successfully, but these errors were encountered:

Thanks for reporting! It'll be about a few days before I can look into this (since we're all trying to make IROS 22 deadlines), but it looks like it should be a simple fix.

SarveshS325 · 2022-03-16T06:05:43Z

Any idea where the problem could be arising from?

frank-Regal · 2022-03-17T17:14:51Z

also getting the same error when building, any resolution?

dellaert · 2022-03-18T00:47:59Z

@varunagrawal we don’t’ have to “git clone” with some sub tree flag, right? At least, I remember it works out of the box for me.

varunagrawal · 2022-03-18T04:55:27Z

@SarveshS325 the issue is that you're using a conda environment, so you'll need to specify the values for GTSAM_PYTHON_VERSION and PYTHON_EXECUTABLE in CMake (using ccmake for example).

SarveshS325 · 2022-03-18T06:52:34Z

@varunagrawal, if that were the case I should not have been able to build python bindings either. I have tried with system python3 outside conda environment and setting the GTSAM_PYTHON_VERSION variable, same result.

varunagrawal · 2022-03-18T12:39:46Z

Fair point. Can you please share the GTSAM branch and commit you are trying to build?

SarveshS325 · 2022-03-18T13:04:10Z

I am building from the source archive of the 4.1.1 release

varunagrawal · 2022-03-18T13:23:46Z

Oh then it seems like a bug creeped in that was subsequently fixed. We don't have a CI for Matlab which is why it wasn't caught before, so I apologize for that.

Do you mind building the latest develop branch? It should have the fixes and there should be no impact to your existing code.

varunagrawal · 2022-03-18T14:18:16Z

Quick update: even develop has some issues :-( I'll put in a PR in a few minutes.

SarveshS325 · 2022-03-18T14:20:08Z

Yup, just checked.
Also, there is another related issue in the latest commit when GTSAM_UNSTABLE_INSTALL_MATLAB_TOOLBOX is ON

CMake Error at matlab/CMakeLists.txt:95 (matlab_wrap):
  matlab_wrap Function invoked with incorrect arguments for function named:
  matlab_wrap

varunagrawal · 2022-03-21T17:55:28Z

@SarveshS325 @frank-Regal can you please try with the latest develop?

SarveshS325 · 2022-03-22T08:51:15Z

@varunagrawal No, still the same issue

Can you please post the error message?

SarveshS325 · 2022-03-22T11:15:16Z

It is the same as in the original issue

varunagrawal · 2022-03-22T12:30:18Z

Can you change that line in matlab_wrap.py to from gtwrap.matlab_wrapper.wrapper import MatlabWrapper?

varunagrawal · 2022-03-22T12:37:44Z

This is very weird, especially since the python wrapper works for you. Both wrappers have a line from gtwrap.X import Y so if your system is able to build the python wrapper, then it should be able to build the Matlab wrapper.

Would you mind clearing your build directory and recompiling from scratch? The CMake cache may not have updated. Also please make sure you're on commit d0a1852.

SarveshS325 · 2022-03-23T03:27:56Z

I have tried starting with a squeaky clean build and I am on d0a1852. Maybe there is a difference between how pybind_wrap.py and matlab_wrap.py are being invoked

I have the same problem, is there a solution now?

@SarveshS325 @wxchencn I recently made some updates to the wrapper. Can you please try again?

YeXiaoYu539 · 2022-06-27T13:54:31Z

@varunagrawal I have tried the latest version '4.2a7' , but it doesn't seem to be working, the same error occurs.

Thanks for the info. Can you try fixing that Cmake warning? That may actually be your issue (and we should make that an error rather than a warning).

varunagrawal · 2022-07-04T15:31:22Z

If you're using the system python, the fix is to do apt install python3-dev

varunagrawal · 2022-07-04T19:13:51Z

@SarveshS325 @YeXiaoYu539 @frank-Regal I figured out the issue!!! PR #1235 fixes this. 🎉

varunagrawal · 2022-07-05T13:12:17Z

Can you please comment on whether the latest develop branch works for you?

YeXiaoYu539 · 2022-07-06T13:47:43Z
