classifier_sample_known - IndexError: index 1 is out of bounds for dimension 1 with size 1

njan-creative commented 2 years ago

While using the command below for translation, error occurs.

python scripts/classifier_sample_known.py --data_dir path_to_testdata --model_path ./results/model.pt --classifier_path ./results/classifier.pt --dataset brats_or_chexpert --classifier_scale 100 --noise_level 500 $MODEL_FLAGS $DIFFUSION_FLAGS $CLASSIFIER_FLAGS $SAMPLE_FLAGS

what are the dimensions for your output final["sample"]?

I commented out the viz part, as visualization was not working for me, I saved it as npy instead by changing the below code.

gathered_samples = [th.zeros_like(sample) for _ in range(dist.get_world_size())]
dist.all_gather(gathered_samples, sample)  # gather not supported with NCCL
print('Num gathered : ', len(gathered_samples), gathered_samples[0].shape)
samples_npy = [sample.cpu().numpy() for sample in gathered_samples]
save_path = './output/' + number[0] + '.npy'
np.save(save_path, samples_npy[0])

I downloaded the output from the training server and used the below code.. op_npy, and ip_npy are the paths for saved input and output .npy files. However, the heat map does not seem to work.

import numpy as np
from PIL import Image
import matplotlib.pyplot as plt

def visualize(img):
    _min = img.min()
    _max = img.max()
    normalized_img = (img - _min)/ (_max - _min)
    return normalized_img

o_mat = np.load(op_npy).squeeze()
o_mat = np.clip(o_mat,0,1)
imgo = Image.fromarray(np.uint8(o_mat * 255) , 'L')
imgo.show()

i_mat = np.load(ip_npy).squeeze()
imgi = Image.fromarray(np.uint8(i_mat) , 'L')
imgi.show()

diff = i_mat - o_mat
#print(np.unique(diff))
#imgd = Image.fromarray(np.uint8(visualize(diff)*255) , 'L')
imgd.show()

hmap = visualize(diff)
hmap = np.round(hmap,2)
#print(np.unique(np.round(hmap,2)))

plt.imshow(hmap, cmap='hot') #, interpolation='nearest')
plt.show()

I have encountered the same problem. How do you solve this problem?
