`pyassimp.errors.AssimpError: assimp library not found`

I'm trying to set up the environment (INSTALLATION.md), and I get an error when running PYOPENGL_PLATFORM=egl PYTHONPATH='.' python tests/generate_traversibles.py to generate map files:

File ".../.miniconda3/envs/socnavbench/lib/python3.6/site-packages/pyassimp/core.py", line 38, in AssimpLib
    load, load_mem, export, release, dll = helper.search_library()
  File ".../.miniconda3/envs/socnavbench/lib/python3.6/site-packages/pyassimp/helper.py", line 245, in search_library
    raise AssimpError("assimp library not found")
pyassimp.errors.AssimpError: assimp library not found

• I tried deleting the environment, updating my conda to the latest version (using conda update -n base -c defaults conda), and reinstalling; same error message.
• I get the success messages HUNK #3 succeeded at 401 (offset 1 line). Hunk #4 succeeded at 407 (offset 1 line).after running bash patches/apply_patches_3.sh, both before and after applying the pyassimp bug patch, as expected.
• I tried pip installing pyassimp==4.1.4 (the lastest version) just to see what would happen -- same error.
• I tried import pyassimp in the interpreter (python=3.6.9) and get the exact same pyassimp.errors.AssimpError: assimp library not founderror. The error actually also occurs in the interpreter before applying any patches.

I'm wondering if you have ever come across this error? Could it be a problem with pyassimp or the conda env library structure? Thanks so much.

Hmm. Did you install libassimp-dev? This should allow you to have the assimp library on Linux.

Yes, this worked, thank you! I apologize, I must have missed that line in the README.
