Error following ML tutorial

Question

Hi,

I am following this tutorial: https://www.digitalocean.com/community/tutorials/how-to-perform-neural-style-transfer-with-python-3-and-pytorch#step-2-—-running-your-first-style-transfer-experiment

I am having the same problem as posted in the comments.

Originally, the images from this snippet pasted into Jupyter:

content_image = Image(‘{}/images/content/venice-boat.jpg’.format(workingdir)) style_image = Image(‘{}/images/21styles/starry_night.jpg’.format(workingdir)) display(content_image) display(style_image)

were not showing also, but I finally realised this was becasue the Jupyter notebook was created by user science, so home was different to root home, so I setup again in science home and I get the images etc working.

However, when it comes to the point of trying the first style transfer, I get the rror posted in the comments. Here is is:

CalledProcessError Traceback (most recent call last) in () 3 4 # run the command ----> 5 x = subprocess.check_output(cmd, universal_newlines=True)

OK, so I changed the cvall to use python3 not python, and I get the following error instead:

Traceback (most recent call last): File “main.py”, line 287, in <module> main() File “main.py”, line 44, in main evaluate(args) File “main.py”, line 242, in evaluate style_model = Net(ngf=args.ngf) File “/root/style_transfer/PyTorch-Style-Transfer/experiments/net.py”, line 284, in init model += [upblock(ngf*expansion, 32, 2, norm_layer), File “/root/style_transfer/PyTorch-Style-Transfer/experiments/net.py”, line 127, in init kernel_size=1, stride=1, upsample=stride) File “/root/style_transfer/PyTorch-Style-Transfer/experiments/net.py”, line 167, in init self.upsample_layer = torch.nn.Upsample(scale_factor=upsample) AttributeError: module ‘torch.nn’ has no attribute ‘Upsample’
