Hi, @fxia22
When i try training this repo, i found here only can use .ply format,
so i add a python file "convert.py" in ModelNet40 folder (use after unzip ModelNet40 dataset.).

This file had already been tested on my machine (i7-11700 8C16T),
and i can successful run cls mission after convert ModelNet40 dataset.

In detail, this file also check am i successful convert or not, this function approch by check() in 'convert.py',
but it cost so much time (about 900 secs on my machine, the other part about 23 secs.),
if you don't wont it happen, you can disable that.

Also, i add a run 'convert.py' command in your README.md,
and add 4 .txt you already gave in this page #52

If you have any need for convert, pls let me know.

Thanks for releasing the package.

Awesome job!! @wuyiulin
The converting part works well and fast on my MBP M1 using multi-thread.
And the resulting .ply datasets completely works for the model.

Thank you for your reply! I found that there was an issue with the dataset I downloaded, and I have resolved it.
