error creating directory #429

Closed smilesun closed 5 years ago

I have run the saveOMLConfig beforehand, but when I submit jobs, there are always some jobs with error:

[19] "Warning in dir.create(dir, recursive = TRUE) :"                                                       
[20] "  '/tmp/RtmpeMTT5l/cache/datasets' already exists"                                                    
[21] "Error: package or namespace load failed for 'OpenML':"                                                
[22] " .onLoad failed in loadNamespace() for 'OpenML', details:"                                            
[23] "  call: createDir(file.path(cd, \"datasets\"), verbosity)"                                            
[24] "  error: Error creating dir: /tmp/RtmpeMTT5l/cache/datasets"                                          
[25] "Loading required package: methods"

what could be the potential mistake that I have done ?

hope this is no issue anymore. it looks like multiple nodes tried to access a directory.
