Problems uploading a .tar file

Question

I am working with a file in .tar.Z format. I manually changed its name so it would only have the .tar extension, and I'm currently struggling to open it and read the data. I can't seem to find what did I do wrong.

!pip install tslearn  #Library for Time Series

!pip install hmmlearn  #Library for Hidden Markov Models

import pandas as pd
import numpy as np
import time # For optimization purposes
import matplotlib.pyplot as plt
from matplotlib import cm
import pylab as pl
import io

from google.colab import drive

#Jupyter notebook option for display
pd.set_option('display.max_rows', None)
np.set_printoptions(threshold=np.inf)
%matplotlib inline

filename='diabetes-data'

uploaded = files.upload()

columnsNames = [
    'sequenceName',
    'TagIdentificator',
    'timestamp',
    'dateFORMAT',
    'x-coordinate-of-the-tag',
    'y-coordinate-of-the-tag',
    'z-coordinate-of-the-tag',
    'activity'
]

data = pd.read_csv(io.BytesIO(uploaded[filename]+'.tar'),encoding='latin1',header=None,names=columnsNames)

I did some research and ended up adding the "encoding='latin1' when an error about character reading occurred, but I have no idea how to solve this one. Thank you so much!

Answer 1

tar.Z indicates it is not just a tar file but it is additionally compressed. As far as I know it is a zip compression. You might need unzip additionally.
