ImportError: cannot import name 'Sequence' from 'keras.utils' (/usr/local/lib/python3.7/dist-packages/keras/utils/init.py)

Error when importing Sequence. This must be something new of Colab/ keras, or an inconsistency between tensorflow.keras and keras. Since from tensorflow.keras.utils import Sequence would not throw this error.

It seems that keras-video-generators do not support tensorflow> 2.x, google colab always has the latest stable version of tensorflow installed. You need to specify the desired tensroflow version on your notebook, i.e.
%tensorflow_version 1.x

and then:
import tensorflow print(tensorflow.__version__)

Yes. I need to find time to fix this package but I'm very busy for months. Really sorry, I will try to find some times today and this week to fix everything. Le sam. 12 juin 2021 à 12:38, Atzon ***@***.***> a écrit :

That's weird, I use it with TF v2...
I think that the only one problem is that I try to use "keras" if I found it, either tensorflow.keras if not. And it could be the problem. I will take a look

[venujk]

can we solve it by cloning the repository and changing the import statement to from tensorflow.keras.utils import Sequence

This worked for me using the Google collab. After printing out the tensorflow version and seein git is 2.5 I opened /usr/local/lib/python3.7/dist-packages/keras_video/generator.py

I replaced line 18 from keras.utils import Sequence with from tensorflow.keras.utils import Sequence saved it and it now works for me
Used this Stackoverflow as a guide

[metal3d]

I will fix it, sorry for the very high delay, I had too many things ...

[metal3d]

It's now theorically OK for Tensorflow 2.5. I will package a new version as soon as I finish to cleanup the source code to respect better formating, less complexity and so on.

[ZumelzuR]

I saw in the readme the new version v1.1.0, but no tags added.

[metal3d]

I will add the new tag and make a release today.
I'm very sorry for a long time without any answer and no evolution. This year was hard.

I was still getting this error even after the lines were changed. I copied the keras_videos folder in my working directory and this error was resolved.

Hi, i've read to all the code and i think there's no problem with the code but the problem is the package on pypi site haven't update yet with the newst code. here is one of the solution to fix that :

• try to clone this repo
• change the version number in setup.py
• then try to run

python3 setup.py sdist

python3 setup.py install

after that try to import it again, it will works.

or you just need to download source code from here https://github.com/metal3d/keras-video-generators/raw/master/src/keras_video/generator.py if you want just VideoFrameGenerator

and then use it like below, it's works as well

from generator import VideoFrameGenerator

hi sir @metal3d please update the package on pypi with the newest code base
