写在前面
自己的测试环境:
Ubuntu20.04
ROS-Noetic
一、问题描述
自己运行 python
程序时出现如下报错:
File "/home/wong/.local/lib/python3.8/site-packages/evo/tools/file_interface.py", line 34, in <module>
from rosbags.rosbag2 import (Reader as Rosbag2Reader, Writer as Rosbag2Writer)
File "/home/wong/.local/lib/python3.8/site-packages/rosbags/rosbag2/__init__.py", line 11, in <module>
from .reader import Reader
File "/home/wong/.local/lib/python3.8/site-packages/rosbags/rosbag2/reader.py", line 11, in <module>
import zstandard
File "/home/wong/.local/lib/python3.8/site-packages/zstandard/__init__.py", line 39, in <module>
from .backend_c import * # type: ignore
ImportError: zstd C API versions mismatch; Python bindings were not compiled/linked against expected zstd version (10404 returned by the lib, 10502 hardcoded in zstd headers, 10502 hardcoded in the cext)
二、解决方法
出现上述版本的原因是 zstandard
或者 zstd
未安装,或者版本太老了。重新安装zstandard
或者 zstd
即可解决问题。
pip install --force-reinstall zstandard zstd
然后再次执行 python
程序即可。
