Errors

[hrv897]

When running carbon tracker like this:

tracker = CarbonTracker(epochs=100)

correct = 0
wrong = 0
tracker.epoch_start()
for i in range(100):
true_label = id2label[val_labels[i].item()]
img = T.ToPILImage()(val_features[i].squeeze())
inputs = processor(images=img, return_tensors="pt").to(device)
pixel_values = inputs.pixel_values

outputs = model(pixel_values)
logits = outputs.logits
logits.shape
prediction = logits.argmax(-1)
prediction_str = model.config.id2label[prediction.item()]

display(img)
print("Predicted class:", prediction_str)
print("True class:", true_label)
if true_label == prediction_str:
correct += 1
print("correct")
else:
wrong += 1
print("wrong")

tracker.epoch_end()
tracker.stop()

On an Intel(R) Core(TM) i9-10900KF CPU @ 3.70GHz with 16 GB RAM, NVIDIA GeForce GTX 980 Ti and Windows 10 in Jupyter Notebook, I get the following output from CarbonTracker:

Looks like the energiservice api which we use to query the carbon emissions changed their string format. We will release a bug fix. For now, if you change the query method in energidataservice.py in your local installation it should work. You can find this in your installation here C:\Users\user\anaconda3\envs\gpu2\lib\site-packages\carbontracker\emissions\intensity\intensity.py

    def _emission_prognosis(self, time_dur):
        from_str, to_str = self._interval(time_dur=time_dur)
        from_str = from_str.replace(' ','T')
        to_str = to_str.replace(' ','T')
        url = "https://api.energidataservice.dk/dataset/CO2Emis?start=" + from_str + "&end=" + to_str + "&limit=4"
        response = requests.get(url)
        if not response.ok:
            raise exceptions.CarbonIntensityFetcherError(response.json())
        data = response.json()["records"]
        carbon_intensities = [record["CO2Emission"] for record in data]
        return np.mean(carbon_intensities)

The function _emission_prognosis is found in carbontracker/emissions/intensity/fetchers/energidataservice.py. The path shown above is incorrect.

This issue has been addressed in Release v1.2.0. We've phased out support for the energidataserviceapi and transitioned to the ElectricityMaps API. This change ensures better consistency and resolves the timeout issues previously encountered with consecutive requests. Thank you for bringing this to our attention.
