Subplotting image using matplotlib

Question

I have got couple of images stored as an array using cv2.imread from the folder. I want to now display couple of images from the folder using subplots. Here is what I tried

w=10
h=10
fig=plt.figure(figsize=(8, 8))
columns = 4
rows = 5
for i in range(1, columns*rows +1):
    img = malaria_images[i]
    fig.add_subplot(rows, columns, i)
    plt.imshow(img)
plt.show()

The result however looks like this. I am not sure where I went wrong . Any help would be appreciated. Thank you

Does this Plotting images side by side using matplotlib answer your question? — sai

Have you noticed the concept of axes meant as a handle for each subplots? you cannot use plt.imshow — sai

Is the content of the 'malaria_images' variable a file path or an image? — r-beginners

I've modified your solution to what is in the comments. Does this not show up?

import matplotlib.pyplot as plt

w=10
h=10
#fig = plt.figure(figsize=(8, 8))
columns = 4
rows = 5

fig, axes = plt.subplots(rows, columns, figsize=(8, 8))

i = 0
for r in range(rows):
    for c in range(columns):
        axes[r,c].imshow(malaria_images[i])
        i += 1

plt.show()
