No output for OCRmyPDF

I'm using OCRmyPDF to extract text form scanned pdf files. I use codes from this Colab notebook for that purpose. The only difference is that instead of downloading the pdf file from an online url, I use the pdf file stored on my local machine (replaced it {file_name} instead of {invoice_pdf}). Everything looks fine up to the point I run:

os.system(f'ocrmypdf {file_name} output.pdf')

Instead of 0, I get 512! and the next line, when I run !ocrmypdf Performance Evaluations.pdf output.pdf , I get an unrecognized error message which reads like:

usage: ocrmypdf [-h] [-l LANGUAGE] [--image-dpi DPI]
                [--output-type {pdfa,pdf,pdfa-1,pdfa-2}] [--sidecar [FILE]]
                [--version] [-j N] [-q] [-v [VERBOSE]] [--title TITLE]

                input_pdf_or_image output_pdf
ocrmypdf: error: unrecognized arguments: output.pdf

Finally, running the following line:

with pdfplumber.open('output.pdf') as pdf:
    page = pdf.pages[0]
    text = page.extract_text(x_tolerance=2)
    print(text)

returns

FileNotFoundError                         Traceback (most recent call last)

      3     text = page.extract_text(x_tolerance=2)
      4     print(text)

/usr/local/lib/python3.6/dist-packages/pdfplumber/pdf.py in open(cls, path_or_fp, **kwargs)
     56     def open(cls, path_or_fp, **kwargs):
     57         if isinstance(path_or_fp, (str, pathlib.Path)):
---> 58             fp = open(path_or_fp, "rb")
     59             inst = cls(fp, **kwargs)
     60             inst.close = fp.close

FileNotFoundError: [Errno 2] No such file or directory: 'output.pdf'

Any help is appreciated. Thanks

If the file name contains spaces, then you need to enclose the name in quotation marks.

ocrmypdf "Performance Evaluations.pdf" output.pdf

or

ocrmypdf 'Performance Evaluations.pdf' output.pdf
