Hello,

I have to convert the variable input to an array with dtype float64.

The variable input is as below:

[code]print input
[  6.36505950e+10   6.36505951e+10   6.32830000e+01 ...,   0.00000000e+00
0.00000000e+00   0.00000000e+00]

FV = np.array(input)
print FV
[  6.36505950e+10   6.36505951e+10   6.32830000e+01 ...,   0.00000000e+00
0.00000000e+00   0.00000000e+00]

print type (FV)
<type 'numpy.ndarray'>
print FV.dtype
|S109[/code]

As you can see, elements type of FV array is |S109. How can i convert elements type to float64 ?

I tried :

FV = np.array(featureVector, dtype=np.float64)

but it doesn't work.

Note: the print do not display all elements of input variable (see the ellipsis ...) because there are many elements (38 elements).

thank you for your help,

input is reserved Python word - built-in function. You are overwriting it.

Ok i'll replace "input" by "test". it's the same result.

print test
[  6.36505950e+10   6.36505951e+10   6.32830000e+01 ...,   0.00000000e+00
0.00000000e+00   0.00000000e+00]

FV = np.array(test)
print FV
[  6.36505950e+10   6.36505951e+10   6.32830000e+01 ...,   0.00000000e+00
0.00000000e+00   0.00000000e+00]

print type (FV)
<type 'numpy.ndarray'>
print FV.dtype
|S109

How can i set elements type as float64 ?

.astype()?
