load_resource function not found as a class method of FPDF

问题

The load_resource function is not a listed method in the FPDF library, which is why you're encountering the "Unresolved attribute reference" error in PyCharm. This function does not exist in the standard FPDF library, so you won't find it in the dir(FPDF) output.

You've mentioned that you're trying to override the load_resource method, but it seems like the original library doesn't have such a method. You might want to check if the library you're using, or any custom modifications you've made to it, includes this method or if there's a different method you should be overriding to achieve your intended functionality.

I am looking at the answer to the following question: https://stackoverflow.com/questions/47195075/insert-base64-image-to-pdf-using-pyfpdf

The answer suggested here was to override the existing load_resource method.

What I did instead was

class EnhancedPdf(FPDF):

    def load_resource(self, reason, filename):
        if reason == "image":
            if filename.startswith("data"):
                f = filename.split("base64,")[1]
                f = base64.b64decode(f)
                f = BytesIO(f)
                return f
            else:
                return super().load_resource(reason, filename)

However, Pycharm highlights the super call with the message "Unresolved attribute reference "load_resource" for class "FPDF"

In my command line, I ran the commands

from fpdf import FPDF
   dir(FPDF)

Inspecting this list, I see load_resource function is indeed not a listed method. Hence my question is why is the load_resource function not visible?

Most probably you are using Python 3.x where x >= 5.

On the pypi it says that the module has only experimental support for python 3.y where y <= 4.

Try it with python 2.7 and it might work.

PS: Better try https://pypi.org/project/fpdf2/, the updated version. For bugs or issues see https://github.com/alexanderankin/pyfpdf.

If you really want to use the old version, you can install whatever version you want from the original repo like this

pip install git+https://github.com/reingart/pyfpdf@<branchname of tag or commit>
