After I install the repo using:
$ pip install .
and run my code, I get the following error:
    Running setup.py install for torch-encoding ... done

(torchenc) mona@goku:~/research/code/PyTorch-Encoding$ python test_demo.py 
Traceback (most recent call last):

ModuleNotFoundError: No module named 'encoding.version'




This is the test_demo.py code:
import torch
import encoding

# Get the model
model = encoding.models.get_model('DeepLab_ResNeSt269_PContext', pretrained=True).cuda()
model.eval()

# Prepare the image
url = 'https://github.com/zhanghang1989/image-data/blob/master/' + \
      'encoding/segmentation/pcontext/2010_001829_org.jpg?raw=true'
filename = 'example.jpg'
img = encoding.utils.load_image(encoding.utils.download(url, filename)).cuda().unsqueeze(0)

# Make prediction
output = model.evaluate(img)
predict = torch.max(output, 1)[1].cpu().numpy() + 1

# Get color pallete for visualization
mask = encoding.utils.get_mask_pallete(predict, 'pascal_voc')
mask.save('output.png')


Can you please guide how to fix it?
Here are my pip freeze results. I am aware of ninja: build stopped: subcommand failed. · Issue #162 · zhanghang1989/PyTorch-Encoding · GitHub 1 but I am hoping we can make this work for the newer versions of packages.
