3 years ago So do I, and when I execute the following command: [PYOPENGL_PLATFORM=egl PYTHONPATH='.' python executables/run_all_tests.py.] for testing, the above error also appears. The configuration environment is the same as yours.

3 years ago Thank you for your interest in our work!
As discussed in this resolved GitHub issue the "error" you mentioned is expected to print (we have the same error message print on our end as well). It is a sign of the code working correctly- if you navigate to the session directory for the test you ran, you should see a complete set of plots, metrics, etc. from the test running successfully.
With regards to running your code on CPU, this codebase must be run on a machine with a GPU for the image rendering engine to work.

I know that the error is a sign that code works correctly.But when I run your test file _executables/run_all_tests.py_, every time I use the _Visual-Navigation-Release-master/mp_env/render/swiftshaderrenderer.py script, I get this result,such as:
Running test test_obstacle_map.py ERROR:root:Loading building from obj file: PATH/TO/LB_WayPtNav_Data/stanford_building_parser_dataset/mesh/area3/41a8012778ff4fc1800a7794bd15d81e.obj ERROR:root:#Meshes: 90 Exception ignored in: <bound method Shape.__del__ of <mp_env.render.swiftshader_renderer.Shape object at 0x7fa83855e550>> Traceback (most recent call last): File "/home/lzf/文档/Visual-Navigation-Release-master/mp_env/render/swiftshader_renderer.py", line 157, in __del__ File "/home/lzf/anaconda3/envs/venv-mpc/lib/python3.6/site-packages/pyassimp/core.py", line 351, in release ImportError: sys.meta_path is None, Python is likely shutting down Execution time for test test_obstacle_map.py is 15 seconds.
This ImportError bothers me.So I think it may be that there is something wrong with the dataset itself during the download process. In fact, I don't know exactly why.

3 years ago Hello,
These lines print out on our end as well, when the script executes as expected. It is an issue that occurs at the end of script execution (after all tests, plots are created, metrics are computed, etc.). If you run "run_all_tests.py" and receive no assertion errors that means your code is working correctly.
You can try running this particular test "PYTHONPATH='.' python tests/test_obstacle_map.py" and change visualize=True in this line. If you see a plot, your code has certainly worked.

3 years ago I have changed visualize=True in this line,but I get such errors:

3 years ago Hi Varun! I'm getting the same error here and it looks like the thing we're trying to visualize isn't implemented?
Setting visualize to true, I get here:
`if visualize:
occupancy_grid_nn = obstacle_map.create_occupancy_grid()
fig = plt.figure()
ax = fig.add_subplot(121)
obstacle_map.render(ax)
ax = fig.add_subplot(122)
ax.imshow(occupancy_grid_nn, cmap='gray', origin='lower')
ax.set_axis_off()
plt.show()`Then, if I arbitrarily pass in an argument, I get to this function:
`@staticmethod
def create_occupancy_grid(pos_n3, **kwargs):
"""
Create egocentric occupancy grids at the positions
in pos_n3.
"""
raise NotImplementedError`Do you know what occupancy_grid_nn was meant to be for visualization purposes?
I have followed the instruction and established the environment successfully. When I run the command
PYOPENGL_PLATFORM=egl PYTHONPATH='.' python executables/rgb/resnet50/rgb_waypoint_trainer.py test --job-dir reproduce_LB_WayptNavResults --params params/rgb_trainer/reproduce_LB_WayPtNav_results/rgb_waypoint_trainer_finetune_params.py -d 0I got an Error:some times I also got results:

I have tried running under CPU only mode, but failed. What should I do next?
