Issue
I have defined a function which prints the movie recommendation based on the input movie.
app=Flask(__name__)
@app.route("/")
def recommend(movie_title):
print("for movie({})".format(movie_title))
print("Top 10 movies recommended are")
movie_title_rating=final_movie_table["{}".format(movie_title)]
related_movies=final_movie_table.corrwith(movie_title_rating)
corrwith_movie= pd.DataFrame(related_movies, columns=["Correlation"])
corrwith_movie.dropna(inplace=True)
corrwith_movie=corrwith_movie.sort_values("Correlation", ascending=False)
corrwith_movie=corrwith_movie.join(mean_rating["rating count"])
print(corrwith_movie[corrwith_movie["rating count"]> 50].sort_values("Correlation", ascending=False))
app.run(debug=True)
The function runs just fine
but when I run the above code using flask to run my API the following error pops up
* Serving Flask app "__main__" (lazy loading)
* Environment: production
WARNING: This is a development server. Do not use it in a production deployment.
Use a production WSGI server instead.
* Debug mode: on
* Restarting with windowsapi reloader
An exception has occurred, use %tb to see the full traceback.
It would be really helpful if some one could help me out with this.
Thank you!
Solution
In your function, you do not define the variable.
@app.route("/")
def recommend(movie_title):
Where is movie_title comming from?
You need to pass the information to the server, And then use it in the function. You have two option: Either you do that in the URL: @app.route("/<movie_title>") or you give the name in a json attached to the request:
@app.route("/",methods=['POST'])
def recommend():
movie_title = request.json['title'] #if "title' contains the name
