It seems like that Tensorflow can not be imported

Hi, scGAN is very uesful within my research pipeline and I have being learning and testing it these days. But there is a confusing problem that hardly be solved.
I pulled the docker image from DockerHub, created a container, altered the parameters.json file and copied the data.h5ad file into the container. However, when I ran the following command the error occurred.

docker create -it --name="scGAN_test" bac785b4b3ea /bin/bash

docker cp ./parameters.json 9b1:/scGAN
docker cp ./data.h5ad 9b1:/scGAN

docker exec -it 9b14556fefc4 python main.py

During handling of the above exception, another exception occurred:

Failed to load the native TensorFlow runtime.

See https://www.tensorflow.org/install/install_sources#common_installation_problems

for some common reasons and solutions.  Include the entire stack trace
above this error message when asking for help.

It seems like that importing the Tensorflow may be wrong or because of my wrong manipulations. How to solve it?
Thanks so much!

Hello @duohongrui,
scGANs implementation requires a NVIDIA GPU available.
You can make it available through docker's --gpus flag in any recent docker version.
If you're using an older docker version, you need to use nvidia-docker2 command as replacement for docker.
Please check https://www.tensorflow.org/install/docker?hl=en for more information.
