TypeError: 'NoneType' object is not subscriptable

Great work that you are doing, congrats on that.

I'm testing ECON on windows, and I suffered a lot to build pytorch3d, and mainly the pypoisson. But ended up sucessfully building it, but when executing, I've got this error.

TypeError: 'NoneType' object is not subscriptable

Do you have an idea of how to solve this error? thanks a lot.

Here is the correct running log:

Resume Normal weights from  ./data/ckpt/normal.ckpt 
Resume MLP weights from  ./data/ckpt/ifnet.ckpt 
Complete with  SMPL-X (Explicit) 
SMPL-X estimate with  PIXIE 
Dataset Size: 1

I think you probably forgot to download the ifnet.ckpt or didn't put it under ckpt/data.

Also, you can set use_ifnet=False in econ.yaml, the final results won't be quite different but with faster speed.

[carlosedubarreto]

And it worked awesomely well.

I dont know how I messed that, the ifnet.ckpt was missing and there was a differente normal.ckpt file in the folder. I replaced with the ones in econ_data and it worked.

thanks a lot!!!

@carlosedubarreto

Good to know. Would you mind sharing some hints / pulling a request on How to setup ECON in Windows? This will help other Windows users a lot :)

[carlosedubarreto]

sure, no problem. I have to redo the steps I've done. The pypoisson I still dont know how I made that work (I've been trying for 3 days)

And you mean to make a pull request to add the instruction on the installation part, right?

[YuliangXiu]

Exactly, you could add a new ##Setup on Windows section into docs/installation.md, and list your hints or share your experience here.

My personal experience to install pypoisson is using gcc7, I cannot run it successfully until altering the gcc version.
