not getting results on any stocks

hi, for some reason can't get the sentiment table itself from this code:

BAC = symbols('INTC').sid
bac_sentiment = sentiment[ (sentiment.sid==BAC) ]

only the line:
.sentdex.sentiment[.sentdex.sentiment.sid == 3951].head(10)

can anyone help please? (i am new to quantopian and following on line trainings)

Here's the fix. With some explanation afterwords.

# Append '.peek()' after blaze expressions  

Quantopian recently upgraded our version of Blaze. Unfortunately, the 'implicit computation' feature has been deprecated. This feature allowed users to enter expressions in familiar pandas-like syntax as below


Now, in this latest version, one needs to explicitly tell Blaze to compute the results by appending the peek() method. Here is the text from the Blaze site:

The Expr repr method's triggering of implicit computation has been deprecated. Using this aspect of Blaze will trigger a DeprecationWarning in version
0.10, and this behavior will be replaced by a standard (boring) repr implementation in version 0.11. Users can explicitly trigger a computation to see a
quick view of the results of an interactive expression by means of the peek() method.`

Sorry for the confusion. See attached notebook.
