Encountered a problem while trying to import TensorFlow as 'tf' in Google

For months, I had been using a simple command "import tensorflow as tf" to import tensorflow on my Colab notebook. However, recently, the same code and notebooks started showing an error "from future imports must occur at the beginning of the file".

Upon checking the tensorflow package version using "!pip list", it was "2.8.2+zzzcolab20220719082949".

What baffles me is how a notebook/code that worked flawlessly two weeks ago now suddenly throws errors.

The cell where I encountered this error contained the following code:

import sys
from tflite_model_maker import image_classifier
from tflite_model_maker.image_classifier import DataLoader
from tflite_model_maker.image_classifier import EfficientNetLite0Spec
from tflite_model_maker.image_classifier import EfficientNetLite4Spec
from __future__ import absolute_import, division, print_function, unicode_literals

import matplotlib.pylab as plt
import tensorflow as tf

The error message displayed was:

File "", line 9 import tensorflow as tf ^ SyntaxError: from future imports must occur at the beginning of the file

Answer №1

To resolve the issue, simply move your __future__ import to the beginning of your code:

from __future__ import absolute_import, division, print_function, unicode_literals
import sys
from tflite_model_maker import image_classifier
from tflite_model_maker.image_classifier import DataLoader
from tflite_model_maker.image_classifier import EfficientNetLite0Spec
from tflite_model_maker.image_classifier import EfficientNetLite4Spec

import matplotlib.pylab as plt
import tensorflow as tf

Refer to the future-statements documentation for more information:

A future statement should be placed at the top of the module. The only lines allowed before a future statement are:

  • The module docstring (if applicable)
  • Comments
  • Blank lines
  • Other future statements

In this case, you have other imports preceding your __future__ import, which is not permitted.
