launch cloud point error

[zsdfaker]

Hi, When i run pubColoredPointCloud.launch and any other launch about cloud point i get the following error [ERROR] [1606188321.876162798]: Failed to load nodelet [/airsim_colored_cloudify] of type [depth_image_proc/point_cloud_xyzrgb] even after refreshing the cache: Failed to load library /opt/ros/noetic/lib//libdepth_image_proc.so. Make sure that you are calling the PLUGINLIB_EXPORT_CLASS macro in the library code, and that names are consistent between this macro and your XML. Error string: Could not load library (Poco exception = libblas.so.3: cannot open shared object file: No such file or directory) [ERROR] [1606188321.876223143]: The error before refreshing the cache was: Failed to load library /opt/ros/noetic/lib//libdepth_image_proc.so.

How i should go about it? Thanks, Zsder
