Columns and DataType Not Explicitly Set on line 18 of load_utils.py

Hello!

I found an AI-Specific Code smell in your project.
The smell is called: Columns and DataType Not Explicitly Set

You can find more information about it in this paper: https://dl.acm.org/doi/abs/10.1145/3522664.3528620.

According to the paper, the smell is described as follows:

Example:

### Pandas Column Selection
import pandas as pd
df = pd.read_csv('data.csv')
+ df = df[['col1', 'col2', 'col3']]

### Pandas Set DataType
import pandas as pd
- df = pd.read_csv('data.csv')
+ df = pd.read_csv('data.csv', dtype={'col1': 'str', 'col2': 'int', 'col3': 'float'})

You can find the code related to this smell in this link: https://github.com/MrGiovanni/ModelsGenesis/blob/bea0ec26cccc42b9c408fe02154a88f49ddc1b1d/keras/downstream_tasks/BraTS/load_utils.py#L8-L28.

I also found instances of this smell in other files, such as:

.

I hope this information is helpful!

Start by reading keras/downstream_tasks/BraTS/load_utils.py lines 8-28 and trace how the loaded data is used downstream. Identify the expected columns and data types from the surrounding code, then verify that explicit definitions preserve the existing processing behavior and pass the applicable project checks.
