Error when rendering gan...

lvec = load_vec('/content/drive/MyDrive/projects/stylegan2/datasets/my.npz')
img = render_gan(G, device, lvec)
Error output
----> 2 img = render_gan(G, device, lvec)
...
---> 42 z = torch.from_numpy(lvec).to(device)
TypeError: expected np.ndarray (got NpzFile)

my bad sorted

tried even to download the file and upload to drive still getting same error can you please help me with this.

Hello when running the training i have this error:

I am getting this error while running a code in google colab from one of your youtube videos

ModuleNotFoundError Traceback (most recent call last)

ModuleNotFoundError: No module named 'dnnlib'

Please help me getting the solution of this promblem.

Hey Jeff - I'm reaching out because I'm working on a project where I needed to download Wikipedia and extract links for an entity linking task. I wanted to share some code that I've been working on, some of which I edited from your repo (e.g. download_wikipedia.py), some of which I wrote from scratch (extract_wikipedia.py, etc.). Have a look! I suspect you'll find your beefy CPU machine pinned at 100% utilization.

Thanks for your videos and code.

Hey Jeff. First off, thanks for this awesome notebook to train GANs with simple steps.
After preparing the dataset (with consistent bit depth and image size, no errors for the dataset), I am running into these errors when starting the initial training after the first tick.

/usr/local/lib/python3.7/dist-packages/torch/nn/modules/module.py:1051: UserWarning: Named tensors and all their associated APIs are an experimental feature and subject to change. Please do not use them for anything important until they are released as stable. (Triggered internally at  /pytorch/c10/core/TensorImpl.h:1156.)
  return forward_call(*input, **kwargs)
/usr/lib/python3.7/multiprocessing/semaphore_tracker.py:144: UserWarning: semaphore_tracker: There appear to be 34 leaked semaphores to clean up at shutdown
  len(cache))

Sadly I am not aware of what leaked semaphores are ment to be, nor what the Named tensor problem is. Do you know what is causing this? It stops the colab and doesnt get further than that first tick.

I got this huge error list when trying to train my model for the first time.

need your help for resolution, was working on google colab following your video
