-> Cannot close object, library is destroyed. This may cause a memory leak!

Bug description

I'm trying to run an example of doctr on my M1 Mac. Code is shown farther below.

Code snippet to reproduce the bug

from doctr.io import DocumentFile
from doctr.models import ocr_predictor
import os
# Let's pick the desired backend
os.environ['USE_TORCH'] = '1'

if __name__ == "__main__":

    model = ocr_predictor(pretrained=True)

    # PDF
    doc = DocumentFile.from_pdf("marco-test-2.pdf")

    # Analyze
    result = model(doc)
    # result.show(doc)

Error traceback

`-> Cannot close object, library is destroyed. This may cause a memory leak!`

Hi @marcobornstein :wave:,

Could you please check if this also happens with images ?

[marcobornstein]

Yes, it was not working still for images. However I found that result.synthesize() worked as expected. For example, this code snippet worked:

model = ocr_predictor(pretrained=True)

# PDF
doc = DocumentFile.from_pdf("marco-test-2.pdf")

# Analyze
result = model(doc)
synthetic_pages = result.synthesize()
plt.imshow(synthetic_pages[0]);
plt.axis('off');
plt.show()

@marcobornstein Mh the error disappeared ?

BTW: .show(doc) is now .show()

Seems to be solved -> Feel free to reopen if not :)
