#predict_text doesn't exist?

[DGaffney]

I'm interested in using the #predict_text method on the Indico module and I'm getting the following:

2.2.1 :010 > Indico.predict_text(["Best day ever", "Worst day ever"], ["sentiment", "language"])
NoMethodError: undefined method `predict_text' for Indico:Module
        from (irb):10
        from /usr/local/rvm/rubies/ruby-2.2.1/bin/irb:11:in `<main>'

(Version 0.5.1)

Hi @DGaffney, terribly sorry for the inconvenience. Could you give analyze_text a shot? We made a change very recently. Take a look at the newly updated docs at your convenience.

[sihrc]

@DGaffney are you still having issues?

[DGaffney]

Nope, getting the following stack from the demo on your Github readme:

2.1.4 :007 > Indico.analyze_text(["Best day ever", "Worst day ever"], ["sentiment", "language"])

Getting the SSL error for all calls with my API key, across multiple machines now. I’ve moved on to other things, please let me know if you do get around to fixing this, though. You have an interesting dataset, it would be fun to use it.

Assuming you do have the latest version of the library, it looks like there might be a problem with certs on the client side. We'll also investigate on our side right now in case it's not and get back to you as soon as we reach a conclusion. Thanks for your patience!

[DGaffney]

Running through that I get a potentially relevant error message from your API url (apiv2.indico.io, which I found in your gem’s code on git):

I'm pretty certain this is an issue with your certificate bundle (I ran into this myself on OSX). Seems to be a fairly common issue with Ruby 2.0. I would recommend following this gist: https://gist.github.com/mislav/5026283 and seeing if it resolves your issue.

[DGaffney]

I checked that gist, ran through it, didn't have the issues it was telling me about, updated my certs with that haxxx.se url, and ran it against your server, and then ran that ssl fix script mislav wrote:

I hit your URL directly and got this as well. I understand that it's a common issue but it really smells like it's not the issue and that instead this 503 error is the problem.

[sihrc]

You seem to be making a GET request to our servers, which is not supported. Currently, it's being caught by one of our error handling services which returns the 503 you are experiencing by default. Usually, you would provide an api in the url https://apiv2.indico.io/sentiment and it will attempt to find a server for that api.

In your case, may I suggest trying the request with a POST request with the following url and body:

POST https://apiv2.indico.io/sentiment?key=API_KEY
BODY:
{
     "data": "Sentiment text to run"
}

[DGaffney]

Weird. I haven't made any changes beyond the stated attempts from earlier which didn't yield anything and it is now working:

Huh, that's super odd. Regradless, glad to hear things sorted themselves out. Thanks for opening an issue, and feel free to reach out at any point in time and we'll be happy to help however we can!

[madisonmay]

At the very least we'll try to document the issue as best we can, and point folks to some of the same resources we pointed you to on our documentation pages.
