GroupMerging_old function

[ZhuangTingT]

Hi, thanks for your code! But when I run generate_result.py, the functionGroupMerging_old() missed. I found a similar function called GroupMerging in test_util.py, I use it instead. But in function BlockMergin(), a bug happens as follow:

File "/SGPN/utils/test_utils.py", line 182, in BlockMerging()
if volume[xx,yy,zz]!=-1 and volume_seg[xx,yy,zz]==groupseg[grouplabel[i]]:
ValueError: The truth value of an array with more than one element is ambiguous. Use a.any() or a.all()

May you help me solve it? thanks a lot!!

By the way, when i run valid.py, the first number of each line is nan. Does it mean no instance detected?

Hello, I also encountered the same problem, but I did not get an error after using GroupMerging in the test_util.py, I made the prediction correctly, and the output segpred.obj was relatively correct. But when I use the h5 file made by s3dis for valid, the nan in the picture below appears, I don't know if it's the same problem as you said at the end, have you solved it now?

The two file mingroupsize.txt and pergroup_thres.txt obtained after the valid are as follows
