Assertion failed: (ISEQUAL(norm(normalMap0(nx)), 1.f)), function ProcessPixel, file DepthMap.cpp, line 682

As title, please someone help me.
I am struggling running MvgMvsPipeline.py with DEFAULT preset

[waqarsqureshi]

I have similar error with the default script
/DepthMap.cpp:665: void MVS::DepthEstimator::ProcessPixel(SEACAVE::IDX): Assertion `ISEQUAL(norm(normalMap0(nx)), 1.f)' failed.

Pipeline end

[waqarsqureshi]

tried to change default option from densifypointcloud
openMVS/libs/MVS/DepthMap.cpp:648: void MVS::DepthEstimator::ProcessPixel(SEACAVE::IDX): Assertion `ISEQUAL(norm(normalMap0(nx)), 1.f)' failed.

[waqarsqureshi]

compiled the openMVG with release version and now I am getting

@cdcseacave and clue? what would be the reason. I tried different image resolution, but could not resolve. Here is the full output

The debug build give the following

Ref to #928. My issue in release mode might be different as the Assert Errors are in supressed in the release mode.

Tried to reinstall again and use standard libraries on Ubuntu 24.04. It is have the same error

openMVS/libs/Common/Types.h
Relax the equal tolerance on lib\MVS\Common\Types.h and recompile

#define ZERO_TOLERANCE (1e-6) // (1e-7)
#define FZERO_TOLERANCE 0.001f // 0.0001f

This does not solve the buffer overflow detected error occurred during runtime in release mode. Then I changed to debug and compiled again. I did not get the buffer overflow detected error and it went pass through to create scene_dense.ply.

for the Reconstruction Mesh same error in release mode

In the debug mode it says,

When you switch to Ubuntu 2.04 and follow the installation step with Eigen 3.4.1 (as mentioned in dockerfile too) then compiled without cuda. The algo run with a breeze.

I get this error too on a fresh build on macos (m1). What could one do to fix this?
