Reduce the gap between rows when using matplotlib subplot?

Question

My subplot results

My code

fig,ax = plt.subplots(rows,cols, figsize = [24,24])
plt.subplots_adjust(hspace=0, wspace=0)

for i in range(cols):
    step          


        

Answer 1

The ratio in figsize should be same as the ratio of rows and cols in plt.subplot(rows, cols, figsize). For example, if rows is 2 and cols is 4, then the ratio is 1/2, thus figsize being (15, 7.5)(same ratio) would be good.

Following code is an example.

fig, ax = plt.subplots(2, 4, figsize=(15, 7.5))
for i in range(2):
    for j in range(4):
        img = cv2.cvtColor(cv2.imread(os.path.join('../input/deepfake486326facescleaned', train_df.loc[i*2+j, 'name_path'])), cv2.COLOR_BGR2RGB)
        ax[i][j].imshow(img)
        ax[i][j].set_title(train_df.loc[i*2+j, 'label'])
