Prerequisites

Please answer the following questions for yourself before submitting an issue.

• I am using the latest TensorFlow Model Garden release and TensorFlow 2.
• I am reporting the issue to the correct repository. (Model Garden official or research directory)
• I checked to make sure that this issue has not already been filed.

1. The entire URL of the file you are using

https://github.com/tensorflow/models/tree/master/research/object_detection/packages/tf2/setup.py

2. Describe the bug

I'm using Google Colab. When installing object detection dependencies, the cell output shows that pip installing multiple versions of some libraries such as scipy, six, etc. I was leaving it to finish, but it has already taken hours, the execution still running and can't finish the installation.

3. Steps to reproduce

To reproduce, it's simply by cloning this repo:

!git clone https://github.com/tensorflow/models.git

Then, execute the command to install dependencies using setup.py

%cd models/research
# Compile protos.
!protoc object_detection/protos/*.proto --python_out=.
# Install TensorFlow Object Detection API.
!cp object_detection/packages/tf2/setup.py .
!python -m pip install --use-feature=2020-resolver .

4. Expected behavior

The expected behavior is the installation process finishes and doesn't take a long time.

5. Additional context

Here's the log output from the execution process:

I am facing the same issue on my Kaggle Notebook, which worked well a few days ago.

Me too facing the same issue in my Google COLAB Notebook. Please fix the issue. Already, training the model is taking high duration of time. Now, the installation of pip packages taking longer than training the model.

[Sandell0]

!pip install --upgrade pip
Changed pip version from 21.1.3 to 21.3.1 and that resolved this problem for me.
I was able to run the following command successfully, when before it did not finish even after several hours:

%%bash
cd models/research/
protoc object_detection/protos/*.proto --python_out=.
cp object_detection/packages/tf2/setup.py .
python -m pip install .

If after that you will face an issue with cuDNN initialization, look at this thread for a solution:

I updated the pip first and it works for me. zakzheng ***@***.***> 于2021年11月17日周三 下午9:05写道：
