error on running first example

[Scanf-Myname]

Hello when i am running the first example I meet this problem!

My instructions are as follows： git clone https://github.com/facebookresearch/ParlAI.git cd ParlAI python setup.py develop parlai display_data -t babi:task1k:1

`Traceback (most recent call last): File "d:\硕士\2020夏季\背景对话\parlai\parlai\parlai\core\worlds.py", line 1211, in _create_task_agents task_agents = my_module.create_agents(opt) # type: ignore AttributeError: module 'parlai.tasks.babi.agents' has no attribute 'create_agents'

During handling of the above exception, another exception occurred:

I knowI know this is a file conflict problem, but I don’t know how to solve this problem, I hope to get help, thank you very much

Hm, we don't support windows officially. I would suggest trying to make sure all programs are closed, maybe reboot, or manually deleting that folder and trying again.

I face the same problem . Is there no solution ? I tried deleting the folder and trying again .

I think it's something wrong with windows, when I tried to use my virtual machine to run Linux, these problems were resolved. You can try to install it in the Linux environment

[stephenroller]

It's very odd. I am very unsure why this would be problematic for windows. All the file handles were properly closed before the call to rm.

I met the same problem and solved it manually by editing the original data of parlai. Here are the possible problems:

1. [Problem] Mix use of double slash \\ and single slash \ on windows when using os.path.join. [Solution] str.replace("\\","/")

2. [Problem] PathManager cannot remove files [Solution] ParlAI/parlai/core/build_data.py line 294-295 comment delete(if you really want to delete zip, tar files, do it manually)

   if delete:

   PathManager.rm(fullpath)

3. [Problem] windows cannot support long folder name [Solution] https://knowledge.autodesk.com/support/autocad/learn-explore/caas/sfdcarticles/sfdcarticles/The-Windows-10-default-path-length-limitation-MAX-PATH-is-256-characters.html

Thanks for documenting this.

This worked like charm ! Thank you very much .
