# !pip install git+https://github.com/geetu040/transformers.git@depth-pro-projects#egg=transformers
from transformers import DepthProConfig, DepthProImageProcessorFast, DepthProForDepthEstimation

Load the model and image processor:

checkpoint = "geetu040/DepthPro"
revision = "project"
image_processor = DepthProImageProcessorFast.from_pretrained(checkpoint, revision=revision)
model = DepthProForDepthEstimation.from_pretrained(checkpoint, revision=revision)
device = torch.device("cuda" if torch.cuda.is_available() else "cpu")
model = model.to(device)

Inference:

# inference

url = "https://huggingface.co/spaces/geetu040/DepthPro_Segmentation_Human/resolve/main/assets/examples/man_with_arms_open.jpg"

image = Image.open(requests.get(url, stream=True).raw)
image = image.convert("RGB")

# prepare image for the model
inputs = image_processor(images=image, return_tensors="pt")
inputs = {k: v.to(device) for k, v in inputs.items()}

with torch.no_grad():
  outputs = model(**inputs)

# interpolate to original size
post_processed_output = image_processor.post_process_depth_estimation(
  outputs, target_sizes=[(image.height, image.width)],
)

# visualize the prediction
depth = post_processed_output[0]["predicted_depth"]
depth = (depth - depth.min()) / depth.max()
depth = depth * 255.
depth = depth.detach().cpu().numpy()
depth = Image.fromarray(depth.astype("uint8"))

# visualize the prediction
fig, axes = plt.subplots(1, 2, figsize=(20, 20))
axes[0].imshow(image)
axes[0].set_title(f'Image {image.size}')
axes[0].axis('off')
axes[1].imshow(depth)
axes[1].set_title(f'Depth {depth.size}')
axes[1].axis('off')
plt.subplots_adjust(wspace=0, hspace=0)
plt.show()
