Python RandomForestClassifer-未知标签类型：“连续”错误

Question

I am trying to expand my programming skills and thought I would try machine learning. So this is for learning and not for anything serious. With that said, I am retrieving some information from a sqlite database, then trying to run it through a RandomForestClassifier but I get an error.

line 172, in check_classification_targets raise ValueError("Unknown label type: %r" % y_type) ValueError: Unknown label type: 'continuous'"

my code is as follows:

series= cur.fetchall()
y = [x[1] for x in series]
x = [x[2] for x in series]
y = array(y).astype(float)
x = array(x).astype(int)
rf_model = RandomForestClassifier()
rf_model.fit(x, y)

My arrays are of the shape: y.shape (50,) x.shape (50,)

What am I missing? Searching SO it seems like it needs the y variable in a string format but I still get the error:

"number of samples=%d" % (len(y), n_samples)) ValueError: Number of labels=50 does not match number of samples=1

Answer 1

Figured it out.

I needed to transform the array with X = X[:, None]
