This returns a numpy array:
|
||
|
|
|
||
|
|
```python
|
||
|
|
arr = df["cluster"].to_numpy()
|
||
|
|
```

This returns a numpy array of **unique** values:
|
||
|
|
|
||
|
|
```python
|
||
|
|
unique_arr = df["cluster"].unique()
|
||
|
|
```
|
||
|
|
|
||
|
|
You can also use numpy to get the unique values, although there are differences between the two methods([`df.unique`](pandas.pydata.org/pandas-docs/stable/reference/api/pandas.unique.html) doesn't sort while [`np.unique`](numpy.org/devdocs/reference/generated/numpy.unique.html) does):
|
||
|
|
|
||
|
|
```python
|
||
|
|
arr = df["cluster"].to_numpy()
|
||
|
|
unique_arr = np.unique(arr)
|
||
|
|
```
