API of working gradio App responding with empty error

beelzeebuub · January 8, 2024, 9:52am

I have trained a model for Image classification and I am trying to host it on huggingface. The gradio app I made works fine but the minimal JS API example does not even work. I am following a tutorial from Jeremy Howard, and everything looks so straight forward, but wont work in the huggingface space I am using. I think this may have something to do with the job queue that should handle my API calls?

Please someone point me in the right direction I could not find anything on this problem on the forum or in the documentation.

Thank you all in advance.

my code:

# %% ModelTester.ipynb 1
from fastai.vision.all import *
import gradio as gr

# %% ModelTester.ipynb 3
from fastai.metrics import Metric

class OrdinalRegressionMetric(Metric):
    def __init__(self):
        super().__init__()
        self.total = 0
        self.count = 0

    def accumulate(self, learn):
        # Get predictions and targets
        preds, targs = learn.pred, learn.y

        # Your custom logic to convert predictions and targets to numeric values
        preds_numeric = torch.argmax(preds, dim=1)
        targs_numeric = targs

        # Calculate the metric (modify this based on your specific needs)
        squared_diff = torch.sum(torch.sqrt((preds_numeric - targs_numeric)**2))

        # Normalize by the maximum possible difference
        max_diff = torch.sqrt((torch.max(targs_numeric) - torch.min(targs_numeric))**2)

        # Update the metric value
        self.total += squared_diff
        #print("self.total: ",self.total)
        self.count += max_diff
        #print("self.count: ",self.count)
    @property
    def value(self):
        if self.count == 0:
            return 0.0  # or handle this case appropriately
        # Calculate the normalized metric value
        metric_value = 1/(self.total / self.count)
        return metric_value

# %% ModelTester.ipynb 4
learn = load_learner("textfile3-2.pk1")

# %% ModelTester.ipynb 6
categories = ("1","1-2","2","2-3","3","3-4","4","4-5","5")

def classify_image(img):
    pred, idx, probs = learn.predict(img)
    return dict(zip(categories, map(float, probs)))

# %% ModelTester.ipynb 8

intf = gr.Interface(fn=classify_image, inputs='image', outputs='label')
intf.launch(inline=False)

the generated API example:

import { client } from "@gradio/client";

const response_0 = await fetch("https://raw.githubusercontent.com/gradio-app/gradio/main/test/test_files/bus.png");
const exampleImage = await response_0.blob();
						
const app = await client("https://beelzeebuub-fjgradiominimal.hf.space/--replicas/3xqpt/");
const result = await app.predict("/predict", [
				exampleImage, 	// blob in 'img' Image component
	]);

console.log(result.data);`
