No module 'keras.engine'

[lrpalmer27]

trying to run the demo file to get started. Running into this error in the mrcnn/model.py file. Has anyone seen this before? I cant seem to find keras.engine to install.

21 import keras.backend as K
 22 import keras.layers as KL

---> 23 import keras.engine as KE
24 import keras.models as KM
26 from mrcnn import utils

ModuleNotFoundError: No module named 'keras.engine'

Have you found how to solve it？

[lrpalmer27]

I did not solve this issue directly. I think it was regarding an installation error. I made a fork of an MRCNN repo compatible with TF2.0.0+ which works, I have included extra details on all dependency versions I am running (winOS).

This problem is caused by Keras version, the default requirement.txt does not detect version so you should specify version.
here you can find the edited requirement.txt

It doesnt solve keras.engine module problem, unfortunately (for me on google colab)

[Rial-Ali]

What is the problem? can you give me more information? @AvivTahar

[AlicanAKCA]

I've faced with the same error as well.

You can run these commands which are in the readme.md file. Don't forget to try on colab.

Did you try to specify the Keras version?!!!

Hello,
I had the same problem with keras.engine, then updated with specified the versions you were mentionning to, and now I have an other ImportError:

Sorry to hear that.
But I think, your Python Version is wrong.
check your version and downgrade it to 3.4.

hello, did you solve this issue? how?

[coderboyisongithub]

how to solve this on google colab?

[LiuxinYLX]

Hello everyone, I think I have solved this problem. My system is Linux. The version installed of Python is 3.8.19.
I installed :

requirements.txt
pip install keras==2.3.1 tensorflow==1.15.0
pip install protobuf==3.20.3
pip install pycocotools
pip install h5py==2.10.0

You could have a try!

[gamugamu]

Hello, I think the dependency are still buggy. So I made a clean install like your project asked:

Python 3.4, TensorFlow 1.3, Keras 2.0.8 and other common packages listed in requirements.txt.

For my part, I had to change protobuf==3.20 : seems missing.

ERROR: Could not find a version that satisfies the requirement **protobuf==3.20** (from versions: 2.0.0b0, 2.0.3, 2.3.0, 2.4.1, 2.5.0, 2.6.0, 2.6.1, 3.0.0a2, 3.0.0a3, 3.0.0b1, 3.0.0b1.post1, 3.0.0b1.post2, 3.0.0b2, 3.0.0b2.post1, 3.0.0b2.post2, 3.0.0b3, 3.0.0b4, 3.0.0, 3.1.0, 3.1.0.post1, 3.2.0rc1, 3.2.0rc1.post1, 3.2.0rc2, 3.2.0, 3.3.0, 3.4.0, 3.5.0.post1, 3.5.1, 3.5.2, 3.5.2.post1, 3.6.0, 3.6.1, 3.7.0rc2, 3.7.0rc3, 3.7.0, 3.7.1, 3.8.0rc1, 3.8.0, 3.9.0rc1, 3.9.0, 3.9.1, 3.9.2, 3.10.0rc1, 3.10.0, 3.11.0rc1, 3.11.0rc2, 3.11.0, 3.11.1, 3.11.2, 3.11.3, 3.12.0rc1, 3.12.0rc2, 3.12.0, 3.12.1, 3.12.2, 3.12.4, 3.13.0rc3, 3.13.0, 3.14.0rc1, 3.14.0rc2, 3.14.0rc3, 3.14.0, 3.15.0rc1, 3.15.0rc2, 3.15.0, 3.15.1, 3.15.2, 3.15.3, 3.15.4, 3.15.5, 3.15.6, 3.15.7, 3.15.8, 3.16.0rc1, 3.16.0rc2, 3.16.0, 3.17.0rc1, 3.17.0rc2, 3.17.0, 3.17.1, 3.17.2, 3.17.3, 3.18.0rc1, 3.18.0rc2, 3.18.0, 3.18.1, 3.18.3, 3.19.0rc1, 3.19.0rc2, 3.19.0, 3.19.1, 3.19.2, 3.19.3, 3.19.4, 3.19.5, **3.19.6, 4.0.0rc1**, 4.0.0rc2, 4.21.0rc1, 4.21.0rc2, 4.21.0)
**ERROR: No matching distribution found for protobuf==3.20**

So I Switched to protobuf 3.19.6
.
Python 3.4 is no longer maintained and doesn't work with pip3.

I Had to install pycocotools too. It is asked in the demo (# Mask R-CNN Demo). Installed pycocotools-2.0.7.

I post the correct version (who worked for me) on this thread since it's related to requirement.txt / version mismatch.

So the correct version for me is :
Python 3.9.6 (tested first with 3.9.15 and didn't work when load_weights() -> str encode utf8)
tensorflow==1.3.0 like you suggested
keras==2.1.2 for me. (havent retested with Keras 2.0.8 cause of lazyness)

here my requirment.txt:

numpy
scipy
Pillow
cython
matplotlib
scikit-image
**tensorflow==1.3.0**
protobuf==3.19.6
**keras==2.1.2**
h5py==2.10.0
opencv-python
h5py
imgaug
IPython[all]
**pycocotools==2.0.7**

I think you should do an image docker with the repo with the correct python version and the requirment.txt file with the strict version.

Beside that, great project
