Displaying image from local storage

Rasa Open Source

Hello everyone, I am using rasa on telegram. I want to display image from my local storage on telegram. Kindly help me with the same. Thanks.

  1. Copy the telegram.py file in channels to your project. Rename it something like customTelegram.py

  2. In the output channel class, add a new function for sending the image:

def send_image_local(self, recipient_id:Text, image:Text, **kwargs: Any) -> None:
    self.send_photo(recipient_id, open(image, 'rb'))

  1. Add the new item in the dictionary send_functions in the function send_custom_json like ("image_local",): "send_image_local",.

  2. Modify credentials.yml, replacing telegram: with customTelegram.TelegramInput:

  3. In your custom actions use:

attachment = {"image_local": <image_path>}
dispatcher.utter_custom_json(attachment)

That thing is new, I didn’t find it when I made my custom channel. Make a test for the channel with that line commented.

Okay.I’ll give it a try

Hey @ramya,

From what I understood, unless you have your own bot UI, sending image from local folder is not possible. Other channels renders hyperlinks to images only.

So I uploaded the image to imgur, and shared the link in the response and telegram renders the image. It works now.

You can use the imgur api to upload the image within the custom action itself , which return a link that can be sent as a response and telegram will render that image.

( Additionally you may sometimes run into a timeout error like I did,as default time out is 10 sec, imgur may take a bit longer to upload the image. So you can increase the DEFAULT_STREAM_READING_TIMEOUT_IN_SECOND in console.py. Refer this issue )

Cheers.

Wanted to throw in my 2 cents, if (past and future) folks find it helpful.

The bot API by Telegram can actually send images from local disk; you just need to send it as a binary file object. Unfortunately the Rasa channel for Telegram can only send URIs/URLs of images, not file objects. A temporary fix (aka hack =P) is to modify the Rasa connector. Locate telegram.py in the Rasa source on your machine, then find the class TelegramOutput and the method send_image_url, and modify the line that says:

self.send_photo(recipient_id, image)

to

self.send_photo(recipient_id, open(image, 'rb'))

And your bot should be able to send local images to Telegram.
