There are serveral images in the attachment that illustrate the program execution progress and the errors.
Firstly, I create the virtual environment with anaconda, 4.12.0 version .
And I follow the Readme file guide ,
run :
conda install pytorch==1.6
installed the pytorch , the version recorded in the readme file.
run:
python setup.py install
install the required modules for the program :
the result show in Fig1.

After I installed the matplotlib module ,
run:
CUDA_VISIBLE_DEVICES=0 python examples/demo_render.py
Show that files missing, in Fig 2.

Fig2 The error after running command "CUDA_VISIBLE_DEVICES=0 python examples/demo_render.py"
try to run:
bash examples/recon/download_dataset.sh & CUDA_VISIBLE_DEVICES=0 python examples/recon/train.py -eid recon
I can get the terminal result show in Fig 3.

CUDA_VISIBLE_DEVICES=0 python examples/recon/train.py -eid recon"
I try to search fold , file directory /SoftRas/Soft_render/.

There is no such document "soft_renderer.cuda.load_textures" in the folder.
DId I do any steps wrong? Could you point out what went wrong?
