After setting up the tool and sourcing the env_vars.sh as source env_vars.sh, the next step as per the documentation is:

streamlit run https://raw.github.com/amor71/LiuAlgoTrader/master/analysis/backtester_ui.py

Below is the output of the above command:

  You can now view your Streamlit app in your browser.

Thanks for the quick fix. I now have a different error, shown below.

Adding to the previous info, the command pip install liualgotrader executes successfully.

Sure, I'm still trying to figure out. I tried with the python virtual environments and ended up spending several hours trying to get it to work on a plain vanilla Ubuntu Mate 20.04 set up from scratch. I think the documentation/wiki needs more improvement for setup so that it is easy to get started for anyone and I would be happy to contribute once I figure it out.

Below is the issue I'm currently stuck at with the venv style setup.

I am again trying with the conda style setup and again stuck with the same error:

Thanks! That would be super helpful. I have messaged you on Gitter chat.

Got it working, thanks to @amor71.

If anyone is struggling with installation, here's how you can do it on a fresh Ubuntu 20.04 instance:

$ sudo apt update
$ sudo apt install -y apt-transport-https ca-certificates curl gnupg-agent software-properties-common
$ curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -
$ sudo add-apt-repository \
"deb [arch=amd64] https://download.docker.com/linux/ubuntu \
$(lsb_release -cs) stable"
$ sudo apt-get update
$sudo apt install docker-ce -y
$ sudo usermod -aG docker $USER

Log out and log back in

$ sudo curl -L "https://github.com/docker/compose/releases/download/1.28.4/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
$ sudo chmod +x /usr/local/bin/docker-compose
$ sudo add-apt-repository ppa:deadsnakes/ppa
$ sudo apt update
$ sudo apt install python3.9
$ sudo apt install python3-pip
$ sudo apt install python3.9-venv
$ mkdir venv
$ python3.9 -m venv ~/venv/liu
$ source ~/venv/liu//bin/activate
$ mkdir ~/liu ; cd ~/liu
$ pip install liualgotrader
$ export (ALPACA KEYS)=xxx
