ValueError: setting an array element with a sequence. while using SVM in scikit-learn

I have been working on scikit-learn SVMs for a binary classification problem. I have calculated the features of audio files and wrote them into a CSV file. This is how each row in a CSV file looks like:

"13_10 The Long And Winding Road " "[-6.5633095666136669e-16,-1.56E-15,-3.21E-15,-2.20E-
15,-2.52E-15,-3.04E-15,-3.39E-15,-3.47E-15,-3.07E-15,-6.02E-15,-3.00E-15,-4.77E-15,-3.05E-
15,-2.13E-15,-1.57E-15,-1.87E-15,-2.05E-15,-1.76E-15,-1.38E-15,-9.89E-16,-7.89E-16,-8.99E-
16,-1.09E-15,-7.26E-16,-8.68E-16,-4.68E-16,-2.82E-16,-1.99E-16,-1.75E-16,-2.18E-16,-1.43E-
16,-1.56E-16,-1.91E-16,-1.21E-16,-4.82E-17,-4.39E-17,-2.89E-17,-2.05E-17,0.0]" 0

The first column has the name of the Audio, second column has the feature array and the last element is the label {0,1} for binary classification.

There are 39 float values in the array. I am using the following code to extract them from the CSV file.

with open('File.csv', 'rb') as csvfile:
    albumreader = csv.reader(csvfile, delimiter=' ')
    data = list()
    for row in albumreader:
        data.append(row[0:]) 
data = np.array(data)

X_train = list()
Y_train = list()
k = data.shape[0]

for i in range(k):
    feature = data[i][1]
    x = map(float, feature[1:-2].split(','))
    X_train.append(x)
    label = data[i][2]
    y = float(label)
    Y_train.append(y)    

So when I print X_train and Y_train I get exact values in an array. But when I use

clf = svm.SVC(C=1.0, cache_size=200,kernel='linear', max_iter=-1)
clf.fit(X_train,Y_train)

I get the error saying

Traceback (most recent call last):
File "<stdin>", line 1, in <module>

packages\spyderlib\widgets\externalshell\sitecustomize.py",line 540, in runfile

File "C:\Python27\lib\site-packages\numpy\core\numeric.py", line 460, in asarray
return array(a, dtype, copy=False, order=order)
ValueError: setting an array element with a sequence.

Can someone help me as to what I can do now? I am really not sure what is happening inside. Both the dimensions of X_train and Y_train are same [X_train has 21 vectors with 39 elements and Y_train has 21 floats {0 or 1}, I don't see what made these errors.

Note: I have a feeling that something might be wrong while I convert the numpy array to string and then a string to a numpy array. Thanks in advance.

Edit: X_Train is very large. Here it is..
