    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.

Same issue as #9. Can you try, as mentioned there, in a Unix machine? I have only seen this in Windows so far.

sorry,I have some problems about runing train.py .although you have updated the readme.md

Traceback (most recent call last): File "D:\anaconda\envs\object_loader\lib\runpy.py", line 193, in _run_module_as_main "main", mod_spec) File "D:\anaconda\envs\object_loader\lib\runpy.py", line 85, in _run_code exec(code, run_globals) File "D:\google_download\locating-objects\locating-objects-without-bboxes-master\object-locator\train.py", line 78, in env_name=args.visdom_env) File "D:\google_download\locating-objects\locating-objects-without-bboxes-master\object-locator\logger.py", line 56, in init port=port) File "D:\anaconda\envs\object_loader\lib\site-packages\visdom__init.py", line 309, in init__ self.server_base_name = server[server.index("//") + 2:] ValueError: substring not found

I think it might be caused by "--visdom-env mytrainingsession --visdom-server localhost"

[javiribera]

Are you running visdom in your localhost?

Are you running visdom in your localhost? thank you for your help ,now train.py is runing . new problem occurs.I found gpu is used when training.but code gets slow when validation.why gpu is not be used when validation
