Noob needing some help

[TheDovah7]

I am a new python user and I don't understand this error message. The code I have is:

import pandas as pd
import quandl, math
import numpy as np
from sklearn import preprocessing, cross_validation, svm
from sklearn.linear_model import LinearRegression

df = quandl.get("WIKI/GOOGL", authtoken="X5A1-ewy2UCfkFVfGKuW")
df = df[["Adj. Open","Adj. High","Adj. Low","Adj. Close","Adj. Volume",]]
df["HL_PCT"] = (df["Adj. High"] - df["Adj. Close"]) / df["Adj. Close"] * 100.0
df["PCT_change"] = (df["Adj. Close"] - df["Adj. Open"]) / df["Adj. Open"] * 100.0

df = df [["Adj. Close","HL_PCT","PCT_change","Adj. Volume"]]

forecast_col = "Adj. Close"
df.fillna(-99999, inplace=True)

forecast_out = int(math.ceil(0.01*len(df)))

df["label"] = df[forecast_col].shift(-forecast_out)
df.dropna(inplace=True)

x = np.array(df.drop(["label"],1))
y = np.array(df["label"])

x = preprocessing.scale(x)

x = x[:-forecast_out+1]
df.dropna(inplace=True)
y= np.array(df["label"])

print(len(x),len(y))

And the error I am getting is:

Error:
