AttributeError: 'NoneType' object has no attribute 'dtype'

[pythonnewbie3]

Hello, when I run the code I get this error:

AttributeError: 'NoneType' object has no attribute 'dtype'

What can I do?

Hi @pythonnewbie3 Could you add steps to reproduce the error?

Hi @Kohulan The code is:

from decimer_segmentation import segment_chemical_structures, segment_chemical_structures_from_file
import cv2
scanned_page_file_path=r"C:/Users/Username/Desktop/test.pdf"
page = cv2.imread(scanned_page_file_path)
segments = segment_chemical_structures(page, expand=True)
segments = segment_chemical_structures_from_file(path, expand=True, poppler_path=r"C:\Program Files (x86)\poppler-0.68.0\bin")

And the error is:

Traceback (most recent call last):
  File "C:\Users\Username\Anaconda3\lib\site-packages\DECIMER\untitled0.py", line 6, in <module>
    segments = segment_chemical_structures(page, expand=True)

    masks = get_expanded_masks(image)

Thank you.

I just got a new error after changing absolutley nothing:
