As an AI language model, I don't have enough context to understand the specific problem you are facing. However, I can provide you with some general information on this error message.
This error usually occurs when you try to access a specific row or column in a dataframe using a float value as the index. RangeIndex is a type of index that is automatically generated by Pandas when no specific index is provided. It is a sequence of integers starting from 0 and ending at n-1, where n is the number of rows in the dataframe.
Since RangeIndex is an integer-based index, you cannot use float values to access specific rows or columns. To access a specific row or column in a dataframe, you need to use integer-based indexes.
For example, if you want to access the fourth row in a dataframe, you can use the following code:
```
df.iloc[3]
```
Here, iloc stands for "integer location" and returns the row at the specified integer location.
If you want to access a specific column in a dataframe, you can use the following code:
```
df['column_name']
```
Here, 'column_name' is the name of the column you want to access.
In summary, to avoid the "cannot do positional indexing on RangeIndex with these indexers [0.4] of type float" error, you should make sure to use integer-based indexes when accessing specific rows or columns in a dataframe.
