First, if you are using colab, the uploading file method you are using will not work.
Import the following files:
`#import the libraries
import numpy as np
import pandas as pd`
Then include colab libraries
from google.colab import drive
drive.mount("/content/gdrive")
To import you dataset use below line of code.
df = pd.read_csv('/content/gdrive/My Drive/weather_netherlands.csv')
df.head()
