Hi,

this issue has been already reported in the dataset repo (https://github.com/dair-ai/emotion_dataset/issues/2), so this is a bug on their side. The documentation has another bug in the dataset card [here](https://huggingface.co/datasets/emotion). 

In the dataset summary **six** emotions are mentioned: *"six basic emotions: anger, fear, joy, love, sadness, and surprise"*, however, in the datafields section we have only **five**:
```
label: a classification label, with possible values including sadness (0), joy (1), love (2), anger (3), fear (4).
``` @GDGauravDutta the dataset author replied in their issue: https://github.com/dair-ai/emotion_dataset/issues/2
> The dataset released is a preprocessed six emotion variant released for educational and research purposes.

@albertovilla the dataset card was fixed with 6 emotions.
As per documentation,
Dataset: emotion
Homepage: https://github.com/dair-ai/emotion_dataset

Dataset: https://github.com/huggingface/datasets/blob/master/datasets/emotion/emotion.py

Emotion is a dataset of English Twitter messages with eight basic emotions: anger, anticipation, disgust, fear, joy, sadness, surprise, and trust. For more detailed information please refer to the paper.

But when we view the data, there are only 6 emotions, anger, fear, joy, sadness, surprise, and trust.
