3 years ago Saving corresponding image again in the following procedure solved the problem. I checked it in the simulator and it just worked well with no problem!
from PIL import ImageFile from PIL import Image ImageFile.LOAD_TRUNCATED_IMAGES = True
img = Image.open('ac3dc08c7a2646b991fda42ccc42bc47_skybox_depth_small.png') img.save('img_w_no_problem.png')
I have some problems in getting depth data from the simulator. As recommended in the instruction, I first generated depth_skybox images. Using these images, in most cases(both scanId and viewpointId) rendering works well. However in some cases, it fails to read depth data from the data directory.
For example, in 'ScanId: 2azQ1b91cZZ / ViewpointId: ac3dc08c7a2646b991fda42ccc42bc47', when I use this setting in 'src/driver/driver.py' the error shows like below.
_libpng error: Read Error Traceback (most recent call last): File "src/driver/driver.py", line 31, in
sim.newEpisode(['2azQ1b91cZZ'], ['ac3dc08c7a2646b991fda42ccc42bc47'], [0], [0])
ValueError: MatterSim: Could not open skybox depth files at: ./data/v1/scans//2azQ1b91cZZ/matterport_skybox_images/ac3dc08c7a2646b991fda42ccc42bc47_skybox_depthsmall.png
I think the problem is in .png file. I also tried to read the corresponding image file using 'display' command and the error shows like below.

Hope for help.
