Trouble running the Docker image

[ch3njust1n]

I loaded the Docker image with

cat cvpr2021cha_code.tar | sudo docker load

When I checked docker ps, I didn't see anything running and Docker logs showed

sudo docker logs 422402c07084b60ace48a6881017f9c2370b67fcd2a877a575fed557e2468db4
Welcome to SMILELAB SLR Code, please enter
source ./setup_env.sh
/bin/sh: 1: nvidia-smi: not found

I'm not sure which nvidia-smi to install, but these are what my system suggested when I tried running nvidia-smi:
sudo apt install nvidia-340 # version 340.108-0ubuntu5.20.04.2, or
sudo apt install nvidia-utils-390 # version 390.157-0ubuntu0.20.04.1
sudo apt install nvidia-utils-450-server # version 450.248.02-0ubuntu0.20.04.1
sudo apt install nvidia-utils-470 # version 470.199.02-0ubuntu0.20.04.1
sudo apt install nvidia-utils-470-server # version 470.199.02-0ubuntu0.20.04.1
sudo apt install nvidia-utils-525 # version 525.125.06-0ubuntu0.20.04.3
sudo apt install nvidia-utils-525-server # version 525.125.06-0ubuntu0.20.04.2
sudo apt install nvidia-utils-535 # version 535.86.05-0ubuntu0.20.04.2
sudo apt install nvidia-utils-535-server # version 535.54.03-0ubuntu0.20.04.1
sudo apt install nvidia-utils-435 # version 435.21-0ubuntu7
sudo apt install nvidia-utils-440 # version 440.82+really.440.64-0ubuntu6
sudo apt install nvidia-utils-418-server # version 418.226.00-0ubuntu0.20.04.2

I installed nvidia-340 from the list above and got

NVIDIA-SMI has failed because it couldn't communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed and running.

Questions:

1. Could someone point me in the right direction for this nvidia-smi issue?
2. Once I get the container running, how do I send videos to the model? Is there a web server in the container that's serving the model? Do I make a HTTP POST request?
3. How do I batch inputs to the model for production?
