How to show image that's been given as 1-D array

Question

So I have a file with 6 different people, each person having 2 photos (in different angles) thus there are 6 * 2 = 12 images (in B&W).

Each image is 140 (ht) x 120 (width)

When I read the file, all the info is read so I have 12 columns (corresponding to each image) and 16,800 rows (corresponding to the image size).

How do I plot the image on matplotlib ?

I tried extracting each column e.g. df.loc[:,0] and then reshaping it to (140,120). But plotting it gives some abstract art looking output instead of the face. am I doing something wrong?

Answer 1

I've solved it. I think it was a bug/glitch.

So I tried with plt.imshow() and plt.show() but it did not work. I then tried various methods plt.plot() <- which was giving me the weird colour output.

Eventually, going back to plt.imshow() somehow worked
