More Packages are required

[sanchit1053]

installing only the packages listed in the environment.yml is not enough and may lead to error

libGL error: MESA-LOADER: failed to open swrast: /usr/lib/dri/swrast_dri.so: cannot open shared object file: No such file or directory (search paths /usr/lib/x86_64-linux-gnu/dri:\$${ORIGIN}/dri:/usr/lib/dri, suffix _dri)
libGL error: failed to load driver: swrast
GLFW emitted error: GLX: Failed to create context: GLXBadFBConfig
GLFW emitted error: Cannot set swap interval without a current OpenGL or OpenGL ES context
Segmentation fault

We also need to run the command conda install -c conda-forge libstdcxx-ng to make the demos run

Please update the requirements to reflect this
