[Numpy-discussion] ValueError: objects are not aligned

[RuiDC]

I'm getting this error, which must be a simple error in getting the result
from the cursor in the right shape, how do I get the cursor into the array
as a single dimension?: 

    import numpy as np 
    import sqlite3 
    conn = sqlite3.connect("simpledb") 
    cursor1 = conn.execute("select LogReturn from tblReturns limit 3") 
    rf1 = np.asarray(cursor1.fetchall(), dtype=np.float64) 
    print (rf1) 
    print (np.corrcoef([rf1, rf1])) 

result: 
[[-0.00641625] 
 [-0.00498411] 
 [-0.0038015 ]] 
Traceback (most recent call last): 
  File "C:\Documents and Settings\rui\workspace\numpytest\src\numpytest.py",
line 38, in <module> 
    print (np.corrcoef([rf1, rf1]))

    c = cov(x, y, rowvar, bias, ddof)

    return (dot(X, X.T.conj()) / fact).squeeze()
