Value Error: Could Not Broadcast Input Array From Shape (857,3) Into Shape (857)

I've been trying to plot a database that I parsed from a text file into a numpy array. The array has 857 rows. This error keeps popping up, I dont understand what it means. import

Solution 1:

Your dataMatrix is a tuple, so you have two options:

Take the results of the fuction in two different variables:

numpyMat, classLabels = parseFile('kiwibubbles_tran.txt')
fig = plt.figure()

ax = fig.add_subplot(111)
ax.scatter(numpyMat[:,1], numpyMat[:,2])

plt.show()

Plot only the numpyMat from the tuple:

dataMatrix = parseFile('kiwibubbles_tran.txt')
fig = plt.figure()

ax = fig.add_subplot(111)
ax.scatter(dataMatrix[0][:,1], dataMatrix[0][:,2])

plt.show()
