BUG: Compatible Issue

[YingGwan]

I have tried to compile aitviewer in windows and ubuntu 20.04, but encountered same problems:

1. Ubuntu: Anaconda; Python = 3.9.7; Error detail: File "/home/yingjun/anaconda3/envs/test/lib/python3.9/site-packages/_moderngl.py", line 344, in data = b''.join(struct.pack(self._fmt, row) for row in value) TypeError: Value after must be an iterable, not int

2. Windows 10. Anaconda; Python = 3.9.7 Error Detail: File "H:\anaconda3\lib\site-packages\moderngl-5.7.2-py3.9-win-amd64.egg_moderngl.py", line 344, in data = b''.join(struct.pack(self._fmt, row) for row in value) TypeError: Value after must be an iterable, not int

Could you help on this and indicate which version I should use to solve this issue?

I have tried several Python Versions and none of them are successful.

Hi @YingGwan

Thanks for reporting this. I just tested this locally and I was able to reproduce it. It's a problem with moderngl - the latest version seems to have this issue. I was able to resolve this if I downgrade to moderngl 5.6.4, i.e.

pip install moderngl==5.6.4

Can you let me know if this fixes your problem? If so, we'll get this sorted with the next release.

[YingGwan]

This problem has been solved, many thanks!

Good to hear!

I'm opening this again for our reference, to be included in the next release.

The respective bug report in moderngl is: https://github.com/moderngl/moderngl/issues/525 This seems to be a problem as of moderngl version 5.7.1. We can simply fix this by specifying an earlier version in setup.py.

Hi, When I want to load STAR dataset using: pip install git+https://github.com/ahmedosman/STAR.git

It appeared this error: Collecting git+https://github.com/ahmedosman/STAR.git Cloning https://github.com/ahmedosman/STAR.git to c:\users\tiany\appdata\local\temp\pip-req-build-lsrye9fk Running command git clone -q https://github.com/ahmedosman/STAR.git 'C:\Users\tiany\AppData\Local\Temp\pip-req-build-lsrye9fk' Resolved https://github.com/ahmedosman/STAR.git to commit bc6aa8d9be1192ce90d394fdf8898347ec31fe39 ERROR: Command errored out with exit status 1: command: 'H:\anaconda3\python.exe' -c 'import io, os, sys, setuptools, tokenize; sys.argv[0] = '"'"'C:\Users\tiany\AppData\Local\Temp\pip-req-build-lsrye9fk\setup.py'"'"'; file='"'"'C:\Users\tiany\AppData\Local\Temp\pip-req-build-lsrye9fk\setup.py'"'"';f = getattr(tokenize, '"'"'open'"'"', open)(file) if os.path.exists(file) else io.StringIO('"'"'from setuptools import setup; setup()'"'"');code = f.read().replace('"'"'\r\n'"'"', '"'"'\n'"'"');f.close();exec(compile(code, file, '"'"'exec'"'"'))' egg_info --egg-base 'C:\Users\tiany\AppData\Local\Temp\pip-pip-egg-info-0dppz9u7' cwd: C:\Users\tiany\AppData\Local\Temp\pip-req-build-lsrye9fk\ Complete output (5 lines): Traceback (most recent call last): File "", line 1, in File "C:\Users\tiany\AppData\Local\Temp\pip-req-build-lsrye9fk\setup.py", line 24, in long_description = fh.read() UnicodeDecodeError: 'gbk' codec can't decode byte 0x80 in position 3989: illegal multibyte sequence

Could you help with it, many thanks!

Hmm, I cannot reproduce this on my machine unfortunately (also Windows).

What if you clone the STAR repo instead and do python setup.py install in the cloned directory (or pip install -e .)?

[totomobile43]

Since we cannot reproduce this (and it may be a STAR repo issue), I would suggest trying the following:

1. Clone the STAR repo locally
2. Modify the setup.py file as follows: On line 23, replace with open("README.md", "r") as fh: with with open("README.md", "r", encoding="UTF-8") as fh:
3. Run pip install -e

Another thing to make sure is that the path that STAR is placed in should only have ascii characters in it.

hello，great job maker， May i have a question ,when i run Load_STAR, why should i load a STAR Sequece from AMASS data?and i dont know where to get -Female1 run tostand -as a NPZ data.

[kaufManu]

Hi @milkshilin

This is just supposed to be an example to get some pose data. If you find it easier, you could just display a T-pose with STAR as follows:

if __name__ == '__main__':
    star_layer = STARLayer(device=C.device)
    star_seq = STARSequence.t_pose(model=star_layer)
    v = Viewer()
    v.scene.add(star_seq)
    v.run()

You can download the AMASS data from their official website (you will have to create a login and accept a license agreement to do so). The npz file we reference in the code can be obtained by downloading the ACCAD SMPL+H G version on the downloads section of the website.
