inhomogeneous shape about pointnerf

@cwwjyh @cwwjyh I solved this issue.

revise a lot in nerf_synth360_tf_dataset.py

• remove line 384
• change line 401 to proj_mats += [proj_mat_l]
• change line 495 to
  proj_mat_ls, near_far = self.proj_mats[vid], np.array([2.0, 6.0])
• change line 563 to
  proj_mat_ls, near_far = self.proj_mats[id], np.array[2.0, 6.0]

when I ran "bash dev_scripts/w_tt_ft/barn_test.sh ", I got an error.

Traceback (most recent call last): File "test_ft.py", line 354, in main() File "test_ft.py", line 294, in main train_dataset = create_dataset(opt) File "/home/llh/experiments/code/pointnerf-master/run/../data/init.py", line 45, in create_dataset instance.initialize(opt) File "/home/llh/experiments/code/pointnerf-master/run/../data/tt_ft_dataset.py", line 164, in initialize self.proj_mats, self.intrinsics, self.world2cams, self.cam2worlds = self.build_proj_mats() File "/home/llh/experiments/code/pointnerf-master/run/../data/tt_ft_dataset.py", line 417, in build_proj_mats proj_mats = np.stack(proj_mats) File "<array_function internals>", line 200, in stack File "/home/llh/.conda/envs/pointnerf/lib/python3.8/site-packages/numpy/core/shape_base.py", line 458, in stack arrays = [asanyarray(arr) for arr in arrays] File "/home/llh/.conda/envs/pointnerf/lib/python3.8/site-packages/numpy/core/shape_base.py", line 458, in arrays = [asanyarray(arr) for arr in arrays] ValueError: setting an array element with a sequence.

I print "proj_mats", (array([[-2.12008414e+02, 1.42189409e+01, -2.65582607e+01, 3.62517905e+02], [-7.07794035e+01, -1.64727407e+02, 6.40869593e+01, 1.70559990e+02], [-7.23240000e-01, 8.93794000e-02, 6.84789000e-01, 1.77161000e+00], [ 0.00000000e+00, 0.00000000e+00, 0.00000000e+00, 1.00000000e+00]]), array([0. , 4.5]))

It has inhomogeneous shape.

Hi , I also meet this problem, do you address this? if yes, could you give me some advice? Thank you!

@beibeirory hi，I also meet this problem, do you address this? if yes, could you give me some advice? Thank you so much!

np.array([2.0, 6.0]) may not the same in other case, I haven't found elegant soulution for it.

thanks so much，it works!

Hey, I tried what you suggested but still I am getting a similar error. Can you please have a look at it,

pip install numpy==1.23.5 works for me🤗
