Steps to Run on QIMSDK

🟡 Float32 - Model Precision

Download Required Files

File	Save as
Model	esrgan_float.tflite
Input video	ai_demo_sample.mp4

If any downloaded file is a .zip archive, extract it on your host machine before copying: unzip filename.zip

Copy Files to Device

# Replace $HOME to the appropriate device path before running the commands.
# For QLI:    /root
# For Ubuntu: /home/ubuntu
# Modify this based on your platform and ensure files are copied to the correct location on the device.

ssh <user>@<device-ip> "mkdir -p $HOME/{models,media,media/output}"
scp esrgan_float.tflite              <user>@<device-ip>:$HOME/models/
scp ai_demo_sample.mp4  <user>@<device-ip>:$HOME/media/

Connect to device

# Run from your host machine — replace <user> and <device-ip>
ssh <user>@<device-ip>
