Hi all,
I am learning Machine learning Unit 2. May I please ask where can I FIND the csv file in the line in the following code: data = pd.read_csv(‘dataset/test_brakes.csv’)? Seems this is not in the catkin_ws space.
%matplotlib inline
import warnings
warnings.filterwarnings(‘ignore’)
import matplotlib
import matplotlib.pyplot as plt
from matplotlib import cm
from mpl_toolkits.mplot3d import Axes3D
import numpy as np
import pandas as pd
load dataset
data = pd.read_csv(‘dataset/test_brakes.csv’)
#data = pd.read_csv(’/home/user/catkin_ws/src/results/test.csv’)
remove Unmaned column
data.drop([‘Unnamed: 0’], axis=1, inplace=True)
print dataset
plt.figure(figsize=(10, 8))
plt.scatter(data[‘speed’],data[‘distance’])
plt.xlabel("% of max speed of axis 1", fontsize=16)
plt.ylabel(“stop distance [deg]”, fontsize=16)
plt.title(“Dataset”, fontsize=18)
plt.show()
And when I change data = pd.read_csv(‘dataset/test_brakes.csv’) to
data = pd.read_csv(’/home/user/catkin_ws/src/results/test.csv’)
It throws the following errors:
KeyError: “[‘Unnamed: 0’] not found in axis”
Can any of you help? My pose is to run this course on my own ubuntu PC. Cheers
