An attempt has been made to start a new process before the current process has finished its bootstrapping phase. Seems like a bug. #7

Code

from citation_map import generate_citation_map

# This is my Google Scholar ID. Replace this with your ID.
scholar_id = '***********'
generate_citation_map(scholar_id)

The terminal will keep returning the error below for many times. Also, just before the error, the output says something like author profile found, start downloading with a progress bar. Thanks for your help!

Terminal Output:

Author profile found, with 3 publications.

        This probably means that you are not using fork to start your
        child processes and you have forgotten to use the proper idiom
        in the main module:

            if __name__ == '__main__':
                freeze_support()
                ...

        The "freeze_support()" line can be omitted if the program
        is not going to be frozen to produce an executable.

update: setting num_processes=1 seems to solve the problem.

Duplicate of #4

ChenLiu-1996 commented 3 months ago

@GiddaZhang num_processes=1 will make the script very slow. You can take a look at Issue #4.

I looked into this issue again.

It seems that, at least on my side, protecting your main function with if __name__ == '__main__' suffices. Like the following:

from citation_map import generate_citation_map

if __name__ == '__main__':
    # This is my Google Scholar ID. Replace this with your ID.
    scholar_id = '3rDjnykAAAAJ'
    generate_citation_map(scholar_id)

I have updated the README.

I see, it successfully addressed the issue, thx!
