Python command, not found-Git Bash won't run my python files?no Eddit

I am reading a file in python using pandas and then saving it in a numpy array. The file has the dimension of 11303402 rows x 10 columns. I need to split the data for cross-validation and for that I sliced the data into 11303402 rows x 9 columns of examples and 1 array of 11303402 rows x 1 col of labels. The following is the code: tdata=pd.read_csv('train.csv') tdata.columns='Arrival_Time','Creation_Time','x','y','z','User','Model','Device','sensor','gt'] User_Data = np.array(tdata) features = User_Data[:,0:9] labels = User_Data[:,9:10] Get error comes in code: classes=np.unique(labels) idx=labels==classes[0] Yt=labels[idx] Xt=features[idx,:] On the line: Xt=features[idx,:] it says 'too many indices for array' The shapes of all 3 data sets are: print np.shape(tdata) = (11303402, 10) print np.shape(features) = (11303402, 9) print np.shape(labels) = (11303402, 1) How to resolve this, please help.

  Xt=features[idx[:,0],:]
