I can't seem to convert it into an ndarray in numpy, i've read http://docs.scipy.org/doc/numpy/reference/generated/numpy.ndarray.html but it didn't show me how i can convert my input data as shown below into an ndarray.
How to construct a ndarray from a numpy array or a list of integer lists?
*What's the difference between ndarray and array?* I could just use an array type right?
I have a list of integer counts like this
[[1, 2, 4, 1, 5],
[6, 0, 0, 0, 2],
[0, 0, 0, 1, 0]]
And i manage to use this code to create a np.array as shown in http://docs.scipy.org/doc/numpy/reference/generated/numpy.array.html#numpy.array
import numpy as np
x = [[1, 2, 4, 1, 5],
[6, 0, 0, 0, 2],
[0, 0, 0, 1, 0]]
print np.array(x)
[out]:
[[1 2 4 1 5]
[6 0 0 0 2]
[0 0 0 1 0]]
But I can't change it into a np.ndarray with this code:
import numpy as np
x = [[1, 2, 4, 1, 5],
[6, 0, 0, 0, 2],
[0, 0, 0, 1, 0]]
print np.ndarray(x)
I got an error:
Traceback (most recent call last):
File "/home/alvas/workspace/sklearntut/test.py", line 7, in <module>
print np.ndarray(x)
TypeError: an integer is required
How do I create a np.ndarray with the list of integer counts i've got? What integer is the TypeError talking about?
