LoadError: InitError: UndefVarError: pyprogramname not defined

[haonan16]

I am using Ubuntu 18.04.5, Julia v0.6.2, ngsim_env v0.6 branch and following the installation instructions in https://github.com/sisl/ngsim_env/blob/v0.6/docs/install_env_gail_full.md.
I also do some additional setup to make Julia package compatible (Revert to a previous version of *.jl).

1. AutomotiveDrivingModels

• cd ~/.julia/v0.6/AutomotiveDrivingModels
• git checkout 74050e9ae44bda72a485c2573ac4f0df2bc3e767
• change Base.parse() function signature in src/2d/roadway/roadways.jl:35 to line::AbstractString

2. Records

• cd ~/.julia/v0.6/Records
• git checkout 4181e5d8033ddd47c086014301ee2a6c47289e6e

3. Vec

• cd ~/.julia/v0.6/Vec # tag: v0.1.0
• git checkout ab4f652aa12a2d06433e62bb39e0a17f06ca9cbf

4. AutoViz

• cd ~/.julia/v0.6/AutoViz # tag: v0.6.0
• git checkout f04a667b54de3d4b0252b958898577e6243c6f57
• add Reexport to REQUIRE file

5. BayesNets

• cd ~/.julia/v0.6/BayesNets
• git checkout 5febf756d38194712cfb8c0c2294252931611afa

6. NGSIM

• cd ~/.julia/v0.6/NGSIM # tag: v1.1.0
• git checkout 656ead7154bdfef946e51401eeeb4b2c5accb022

7. ~/ngsim_env/julia/deps/build.jl has been modified to include additional required packages.

package_names = [
    "JLD",
    "GridInterpolations",
    "PyCall",
    "PyPlot",
    "Iterators",
    "DataStructures",
    "Parameters",
    "StatsBase",
    "TikzGraphs",
    "CMakeWrapper",
    "Blosc",
    "PGFPlots"
]

I was able to go through all the setup instructions and julia tests julia ngsim_env/julia/test/runtests.jl. However, I ran into the errors when executing the following.

cd ~/ngsim_env/python/tests
python runtests.py

I have searched for the issue but did not find a solution. The errors are
