model info and gt masks errors

[bnespoulous]

Hi there,

I'm trying to rebuild a dataset similar to those of the BOP challenge. For that I generated synthetic images with BlenderProc and now I try to generate the json files I need and the masks. Before executing these scripts on my dataset, i run it on T-LESS dataset to make sure I can use his scripts. After running two scripts, I get the following errors that I can't solve:

• python scripts/calc_gt_masks.py

• python scripts/calc_model_info.py

8/10|08:53:40: Processing model of object 1... Traceback (most recent call last): File "scripts/calc_model_info.py", line 40, in size = map(float, (model['pts'].max(axis=0) - ref_pt).flatten()) TypeError: unsupported operand type(s) for -: 'float' and 'map'

Has anyone encountered this kind of error before, or would know how to fix it?

for the masks it is an error during the installation on the two following modules: apt-get install freetype apt-get install libglfw3

for the model info I changed:

ref_pt = map(float, model['pts'].min(axis=0).flatten()) size = map(float, (model['pts'].max(axis=0) - ref_pt).flatten())

by:

ref_pt = model['pts'].min(axis=0).flatten()
size =(model['pts'].max(axis=0) - ref_pt)

and I have good results
