Tutorial: Classify text with BERT Cannot install dependencies by pip in Colab

[r-matsuzaka]

Hi, I am now tring to run the Classify text with BERT tutorial in Colab. But I got the following error when I run the cell.

import os
import shutil

import tensorflow as tf
import tensorflow_hub as hub
import tensorflow_text as text
from official.nlp import optimization  # to create AdamW optimizer

import matplotlib.pyplot as plt

tf.get_logger().setLevel('ERROR')

---

ModuleNotFoundError Traceback (most recent call last) in <cell line: 7>() 5 import tensorflow_hub as hub 6 import tensorflow_text as text ----> 7 from official.nlp import optimization # to create AdamW optimizer 8 9 import matplotlib.pyplot as plt

ModuleNotFoundError: No module named 'official'

---

NOTE: If your import is failing due to a missing package, you can manually install dependencies using either !pip or !apt.

To view examples of installing some common dependencies, click the "Open Examples" button below.

In the previous cell, when I run !pip install -q tf-models-official==2.11.0 I got the following error.

I could install offcial by !pip install -q tf-models-official. But in the next cell I got the other error... Could you tell me the correct instruction to isntall the dependency?

import os import shutil

import tensorflow as tf import tensorflow_hub as hub import tensorflow_text as text from official.nlp import optimization # to create AdamW optimizer

import matplotlib.pyplot as plt

tf.get_logger().setLevel('ERROR')

The reason is the failure of CI https://github.com/tensorflow/text/commit/978fd9f2ecc334f939946090236f2870ebfe991e

I could run the notebook with the previous versions.

@r-matsuzaka : have you found any workaround? I encountered the same issue: https://github.com/tensorflow/text/issues/1213

@fbernaly here it is: https://github.com/tensorflow/text/issues/1213#issuecomment-1717023160

Thanks @MrDBC, what you suggested works:

Run:

!pip install -U "tf-models-official==2.13.*" --no-deps
