about the color array in the data from shapenetv2

[Lemniscatic]

Dear Sir:
for shape_idx in range(4):
v, f, c, n = objs[rng.randint(0, len(objs))]
v, f, c, n = v.copy(), f.copy(), c.copy(),n.copy()
This code ,I have noticed that after this line the array[c] turn to [], so that this line :
c_idx=rng_clr.randint(ref_len, size=(c.max()+1))#np.full(v.shape[0], )
have made a mistake. I was wondering if it is not necessary regarding the above line, because I found that the part you have called in the data from shapnetv2 does not contain the color information.
I'd really appreciate if you could reply in the midst of pressing affairs.

Thanks a lot
