Simple test doesn't generate .obj fle [error cannot marching cubes]

[AnMa12]

Hello!

I am running the program using: python -m apps.simple_test

It runs and it generates result_test_50.png but the .obj file is not generated

I'm not sure what image you are processing. But seems like surface reconstruction failed on the input image you provided.

The reason this happens is because of a different version of PyTorch. Go to lib/geometry.py and remove the align_corners=True argument

Using old version of scikit-image works for me pip install scikit-image==0.18.3 (same version of my Google Colab).

(Note that it works even with that warn: .../pifuhd/lib/mesh_util.py:77: FutureWarning: marching_cubes_lewiner is deprecated in favor of marching_cubes. marching_cubes_lewiner will be removed in version 0.19 verts, faces, normals, values = measure.marching_cubes_lewiner(sdf, thresh)

For future users who arrive here, please note that #161, #149, and #85 all resolve to the same issue. The skimage.measure method marching_cubes_lewiner from previous versions of skimage has been deprecated and replaced with marching_cubes.

Line 77 of mesh_util.py can be updated as follows and allows users to use up-to-date versions of skimage as well.

currently in repo: verts, faces, normals, values = measure.marching_cubes_lewiner(sdf, thresh) replace to: verts, faces, normals, values = measure.marching_cubes(sdf, thresh, method="lewiner")

If the authors (@shunsukesaito) would like to authorize a pull request I will make the update.

In case anyone in the future is unsure how to modify source files in the Colab environment create a new code cell just before the cell containing !python -m apps.simple_test ... with the following content

%%bash
sed -i 's:marching_cubes_lewiner:marching_cubes:' /content/pifuhd/lib/mesh_util.py
grep 'marching_cubes.' /content/pifuhd/lib/mesh_util.py

There are many ways to fix it in the colab environment, this is just one way that works.
