As the error clearly states: blender can find the file but blender can't read it. I can't tell from here what is wrong with the file

I think maybe the size is a problem as it render normally if I don't increase sub-division or add HDRI. Well here is my Rendered result: https://drive.google.com/file/d/1-TP1894jYfF8WcJH6RTYG9Ji3n1Fw1ri/view?usp=sharing

How I can include the path to bake file in the drive, is there any specific keyword for that?

Put all files into one folder on your local drive. Make all paths relative with blender, save and upload that folder. this way your paths to external files should be platform independant

Will see it in while.Thanks for the quick response :)

i have revised it a bit for my own research purpose. can I make it public in Github (just want to get permission from you first).
really appreciate it!

i didn't improve anything and it doesn't fulfill the same needs. it runs a program that uses blender. It is a program that generates a bunch of dataset called 'Clevr'.

I tried to render in GPU new cycles x in Google Colab, but I can't, this message showed (some suggestions):

• Maybe I have to try the paid version of Colab to avoid queues?

I notice that there are some redundant files gitfile1.txt, gistfile2.txt etc.

That is because exuanbo/[email protected] introduces a bug causing the gist filename to be un empty string if gist_file_name is not provided. It is fixed in v1.1.2 and v1.

@exuanbo Thanks for the info. Will try to clean this up asap
