SavedModel file does not exist when using Tensorflow hub

Question

When trying to use the hub.load function from tensorflow_hub, I get an OSError: SavedModel file does not exist at: error.

The weird thing is that it worked a few days ago, so I don't quite understand why I'm getting this error now.

Code to reproduce:

import tensorflow as tf
import tensorflow_hub as hub

URL = 'https://tfhub.dev/google/universal-sentence-encoder/4'
embed = hub.load(URL)

Specific error received:

Answer 1

So, just deleting that folder and running the hub.load() function again solves the issue

Answer 2

I have tried the above solution, but it didn't work for me...

Here's what worked:

1. Download the model from tfhub.dev with assets, variables and .pb checkpoint file.
2. Make sure you import tensorflow_text module!

import tensorflow_text

3. Specify the downloaded folder path in the hub.load() statement as in:

model = hub.load("/Users/bilguun/Desktop/universal-sentence-encoder-multilingual-large_3/")
