conda python pcl
遇到一个问题折腾很久,记录一下.
环境:ubuntu20.0 python3.8
起因是想运行这个开源代码
https://github.com/Derek-TH-Wang/quadruped_ctrl
但发现找不的pcl.
然后用conda想按照pcl,常用命令,无非就是conda install -c xx python-pcl.
后来在anaconda-navigator中也看到已经安装有pcl了
但就是import pcl 说找不到
后来用各种命令尝试:
conda install -c sirokujira python-pcl --channel conda-forge
也都不行.
不知为何时,突然注意到提示信息:
$ conda install -c sirokujira python-pcl --channel conda-forge

UnsatisfiableError: The following specifications were found
to be incompatible with the existing python installation in your environment:
Specifications:
- python-pcl -> python[version='>=2.7,<2.8.0a0|>=3.6,<3.7.0a0|>=3.5,<3.6.0a0']
Your python: python=3.8
If python is on the left-most side of the chain, that's the version you've asked for.
When python appears to the right, that indicates that the thing on the left is somehow
not available for the python version you are constrained to. Note that conda will not
change your python version to a different minor version unless you explicitly specify
that.
The following specifications were found to be incompatible with your system:
- feature:/linux-64::__glibc==2.31=0
- feature:|@/linux-64::__glibc==2.31=0
Your installed version is: 2.31
好吧,conda还是很厉害的,直接告诉你了原因: python版本不兼容啊.人家要求pcl的版本是
version='>=2.7,<2.8.0a0|>=3.6,<3.7.0a0|>=3.5,<3.6.0a0'
但半小时前,也是过conda新建enviroment,然后用了这个教程:

用了新环境,python3.6版本,走到最后,还是遇到了一个新问题:
ImportError: /home/allen/anaconda3/envs/name_pcl/lib/python3.6/site-packages/pcl/../../.././libpcl_io_ply.so.1.8: undefined symbol: _ZN5boost6system15system_categoryEv
还是没成功啊.
参考知呼帖子:

还没试过用源码安装.
是了用pip3 install python-pcl, 也是报错:
$ pip3 install python-pcl
