error about simple_parsing

[crankler]

Hello, thank you for your teams work, it's really helpful. However, when I run this command `roslaunch elevation_mapping_cupy turtlesim_simple_example.launch in the terminal, I got this error :

terminate called after throwing an instance of 'pybind11::error_already_set'
  what():  ModuleNotFoundError: No module named 'simple_parsing'

I have install simple_parsing with pip, but the error still exists. I still don't know the reason. So do you know how to fix it? Thanks you for your reply.

You just need to install the package with pip install simple-parsing and not with --user. The package should be then here: /usr/local/lib/python3.8/dist-packages/simple_parsing

[crankler]

Tkank you for your help. However, it still doesn't wrok. When I input this command:

Requirement already satisfied: simple_parsing in /home/yc/.local/lib/python3.11/site-packages (0.1.5)
Requirement already satisfied: docstring-parser~=0.15 in /home/yc/.local/lib/python3.11/site-packages (from simple_parsing) (0.15)
Requirement already satisfied: typing-extensions>=4.5.0 in /home/yc/anaconda3/lib/python3.11/site-packages (from simple_parsing) (4.9.0)

and when I launch the file, the error shows here:

terminate called after throwing an instance of 'pybind11::error_already_set'
  what():  ModuleNotFoundError: No module named 'simple_parsing'

By the way, I use the Ubuntu20.04, cuda 12.4, ros-notetic

[georgflick]

seems like you installed it with --user, so you have to uninstall it first, and reinstall it without the --user flag.

pip uninstall simple-parsing typing-extensions docstring-parser and then install it again with pip install simple-parsing should fix the problem.

[crankler]

Yes, when I use conda with python3.8, I reinstall simple-parsing, and it works. Thanks again for your quick reply here.

Hi, @georgflick. Sorry again to bother you, when I launch roslaunch elevation_mapping_cupy turtlesim_semantic_pointcloud_example.launch and roslaunch elevation_mapping_cupy turtlesim_semantic_image_example.launch, there also shows another error:

log file: /home/yc/.ros/log/ddcf14ca-e034-11ee-a3c2-cb8a5cce1b46/front_cam-5*.log

I think it is caused by cupy where I found "File "/usr/lib/python3/dist-packages/scipy/sparse/sputils.py", line 16, in ", but in conda where python is 3.8, I install pip install scipy==1.8, I found:

Requirement already satisfied: scipy==1.8 in /home/yc/.conda/envs/torch38/lib/python3.8/site-packages (1.8.0)
Requirement already satisfied: numpy<1.25.0,>=1.17.3 in /home/yc/.conda/envs/torch38/lib/python3.8/site-packages (from scipy==1.8) (1.21.1)

I means these two installion positon of scipy are not same, and I keep fix this dismatch issue here.

[crankler]

I've solve this issue, just install the commands:

sudo pip3 install simple_parsing
sudo pip3 install numpy==1.21.1
sudo apt-get install ros-noetic-ros-nump

I can launch both command in bash.
