TypeError: Cannot handle this data type: (1, 1, 3), <f4

Question

the temp_image is (600, 600, 3) with values ranging from 0 to 1.

def pro_process(temp_img, input_size):
    img = np.asarray(temp_img).astype('float32')
    img = np.array(Image.fromarray(img).resize((input_size, input_size)).convert(3))
    return img

It gives the following error:

Traceback (most recent call last):
  File "S:\Program Files\Python36\lib\site-packages\PIL\Image.py", line 2681, in fromarray
    mode, rawmode = _fromarray_typemap[typekey]
KeyError: ((1, 1, 3), '<f4')

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "H:\OneDrive\synchronization code\Developing collection\Python\MNet_DeepCDR-master\mnet_deep_cdr_ide\run\Step_3_MNet_test.py", line 56, in <module>

What's the error and how to fix it?

according to this link:PIL TypeError: Cannot handle this data typeI have updated my code, but there still have an error

def pro_process(temp_img, input_size):
print(temp_img.shape)
img = np.asarray(temp_img).astype('float32')
img = np.array(Image.fromarray((img * 255).astype(np.uint8)).resize((input_size, input_size)).convert(3))
return img

error:

  im = self.im.convert(mode, dither)
 TypeError: argument 1 must be str, not int

Answer 1

The error message seems to be complaining about the shape, but it is really about the data type. Multiplying by 255 and then changing to uint8 fixed the problem for me:

random_array = np.random.random_sample(content_array.shape) * 255
random_array = random_array.astype(np.uint8)
random_image = Image.fromarray(random_array)

Answer 2

please try this code:

np.array(Image.fromarray((img * 255).astype(np.uint8)).resize((input_size, input_size)).convert('RGB'))

Answer 3

The issue is with the float (0–1) type of the array. Convert the array to Uint (0–255). The following thread is related: PIL TypeError: Cannot handle this data type

im = Image.fromarray((x * 255).astype(np.uint8))
