I need to convert a part of my data to make it compatible with this solution: <https://stackoverflow.com/a/64854873>

The data is a `pandas.core.frame.DataFrame` with:

```
      result  data_1  data_2
1    1.523     4        1223
3    1.33     84        1534

```

Some index values might be removed, therefore 1, 3, ...

It should be a tuple with data values and the result. The type in the solution was `scipy.sparse._coo.coo_matrix`, like:

```
  (4, 1223) 1.523
  (84, 1534) 1.33

```

Just `scipy.sparse.coo_matrix(df.values)` seems to mix the data.

```
  (0, 0)    1.523
  (0, 1)    1.53
  (0, 24)   1.92
  : :
  (2, 151)  123.0
  (2, 142)  834.0

```

How can I generate a compatible matrix?
