机器学习服务器- RevoScaleR错误

Question

我在Ubuntu中更新了R()，在更新之后，RevoScaleR包停止工作。我试着看日志，但它不存在。有人知道吗？

编辑：我发现没有找到libRblas.so，但它存在于/runtime/R/lib中

library(RevoScaleR)
C++ runtime exception caught: could not open FIFO /tmp/Rtmp9FpGRx/RevoFIFO.140827.2
Error: package or namespace load failed for ‘RevoScaleR’:
 .onLoad failed in loadNamespace() for 'RevoScaleR', details:
  call: dyn.load(linkDllName)
  error: fatal error: RevoScaleR cannot be used in this R session anymore, if possible restart R session
error code 127, detailed error message might be found in: /tmp/Rtmp9FpGRx/stdoutrppZXg (standard output) and /tmp

"RevoScaleR" %in% dir(.libPaths())的输出为TRUE。

结果发现，在更新之后，库神奇地消失了。我通过手动复制必要的库来解决这个问题：

sudo cp /opt/microsoft/mlserver/9.2.1/runtime/R/lib/libmkl_gnu_thread.so /opt/microsoft/mlserver/9.2.1/libraries/RServer/RevoScaleR/rxLibs/x64/libmkl_gnu_thread.so
