python – Creating environment manually on Cloud GPU without conda

I have access to university Cloud GPU which does not have conda installed (and I am not allowed to install it). I am trying to install ChartOCR (github.com/soap117/DeepRule) which comes with a txt file for creating the environment using

conda create  --name DeepRule --file DeepRule.txt  

How do I manually install / replicate the environment on the Cloud GPU without conda? The CloudGPU allows me to use virtual environment using

python3 -m venv --system-site-packages ~/myvenv

This is what I have tried:

python3 -m venv --system-site-packages ~/ChartOCR-env
source ~/ChartOCR-env/bin/activate
git clone https://github.com/soap117/DeepRule
cd DeepRule
pip install -r DeepRule.txt

ERROR: Invalid requirement: '@EXPLICIT' (from line 4 of DeepRule.txt)
