Upload numpy array as grayscale image to S3 bucket
I have made some mathematical operations on some grayscaled images in python using numpy.
Now I want to upload the resulting numpy arrays as png images to my S3 bucket.
I have tried to upload them as base64 formats, but in that way I cannot open them as images from S3. My code looks as follows:
dec=base64.b64decode(numpy_image)
s3.Bucket('bucketname').put_object(Key='image.png',Body=dec, ContentType='image/png',ACL='public-read')
When I try to open the file from S3 it says that the file contains an error
python numpy amazon-s3 bucket

You probably need to convert your numpy array to an image before uploading it to S3. Take a look at this answer: stackoverflow.com/a/2659378/1525432.

So I needed to convert the numpy array into an image first.
The following code turned out to work:
from PIL import Image
import io
img = Image.fromarray(numpy_image).convert('RGB')
out_img = BytesIO()
img.save(out_img, format='png')
out_img.seek(0)
s3.Bucket('my-pocket').put_object(Key='cluster.png',Body=out_img,ContentType='image/png',ACL='public-read')
