I'm trying to read a file and save to a numpy matrix to display it, but I'm stuck on an error.

from matplotlib import pyplot as plt
import numpy as np

image = np.empty((1664, 512, 256), np.uint16)

reader = open('Datasets/burned_wood_with_tape_1664x512x256_12bit.raw', "rb").read()

image.data[:] = reader

plt.imshow(image)

And this returns:

Traceback (most recent call last):
  File "[PATH]", line 8, in <module>
    image.data[:] = reader
NotImplementedError: memoryview slice assignments are currently restricted to ndim = 1

Any ideas of what's causing this error?

Edit:

I am using this SO question to write my program: read and display raw image using python

  • Did you try image[:], because image.data[:] will return a pointer to the memory. I am assuming you will have to assign the value directly. Commented Nov 5, 2020 at 0:07
  • Why are you trying to assign a value to image.data? Who or what suggested that? The data attribute of an array is a low level object that only the most advanced numpy programmers are allowed to touch :) Commented Nov 5, 2020 at 0:48
  • @AnuragReddy This just returns "Memory Error". Commented Nov 5, 2020 at 2:08
  • @hpaulj See my edit please. Commented Nov 5, 2020 at 2:10
  • @hpaulj Is there a way to assign it directly? Like iterate through the data and assign each index. Commented Nov 5, 2020 at 21:06
