What is your file folder tree like?
And how did you enter the command?

[AsiDiaz]

I have the same issue, I have a folder with all the pcd files and the bin folder is empty. This is the command I used: python3 pcd2bin.py --pcd_path={"/home/asier/rosbag2pcd2bin_converter/pcd_files"} --file_name={"0000000000"}

I changed the default bin path in the code to /home/asier/lidar_bin.

Same as AsiDiaz said, i'm using the command like this "python3 pcd2bin.py --pcd_path=~/Escritorio/PcdToBin/1531799410.004783000.pcd --bin_path=Binarios --file_name=test"

[Yuseung-Na]

I've used like python pcd2bin.py --pcd_path=/home/user/lidar_pcd --bin_path=/home/user/lidar_bin --file_name=convert

Then, converted ".bin" files are saved at /home/user/lidar_bin as "convert_00000.bin, convert_00001.bin, ..."

[JoseM1219]

What version of python are you using??
I'm using Python 3.8.10 and i runned this command
"python3 pcd2bin.py --pcd_path=/home/user/Escritorio/PcdToBin --bin_path=/home/user/Escritorio/lidar_bin --file_name=convert"
and this happened:

I've evaluated my code with python version 2.7 in both Windows 10 and Linux Ubuntu 18.04 using Anaconda envs.

I will try that, thank you so much!!

[Yuseung-Na]

I should test with python 3.x..
Maybe pypcd will make error with python 3.x if install by pip.

If you do that, please let me know. It would be awesome!!

hello, i came across this repo to try and help me change pcd files to bin. I have pip installed pypcd but i am getting an error at the moment saying:

if you have come across this that would be amazing. Thank you

[mreece813]

i was able to fix the pypcd error. I was able to clone a pypcd repo inside of this repo. then have to change line 15 from:
import pypcd to
from pypcd import pypcd
this is the clone repo:
!pip install --user git+https://github.com/DanielPollithy/pypcd.git

It is comes from DATA type.

Here is the same issue as yours.

hey @Yuseung-Na

i used this line to input my pcd file and mention the output folder directory and file name
python pcd2bin.py --pcd_path=C:\Users\91828\Downloads\New folder\pcd --bin_path=C:\Users\91828\Downloads\New folder\bin --file_name=test123

but I'm getting this 'unrecognized argument' error
usage: pcd2bin.py [-h] [--pcd_path PCD_PATH] [--bin_path BIN_PATH] [--file_name FILE_NAME] pcd2bin.py: error: unrecognized arguments: folder\pcd folder\bin

can u help me out of this situation

[Yuseung-Na]

I think you should erase 'space' such as "New folder" in the path.
Please change "New folder" to "New_folder" or something.
