R 机器学习服务器 - RevoScaleR 错误

Question

我已在 Ubuntu 中更新了 R(Microsoft 机器学习服务器 R)，更新后 RevoScaleR 软件包停止工作。我尝试查看日志，但它不存在。有人知道吗？

编辑:我发现 libRblas.so 未找到，但它存在于/runtime/R/lib

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。

事实证明，更新后，这些库神奇地消失了。我通过手动复制必要的库解决了这个问题:

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
sudo cp /opt/microsoft/mlserver/9.2.1/runtime/R/lib/libRblas.so /opt/microsoft/mlserver/9.2.1/libraries/RServer/RevoScaleR/rxLibs/x64/libRblas.so
sudo cp /opt/microsoft/mlserver/9.2.1/runtime/R/lib/libmkl_gf_lp64.so /opt/microsoft/mlserver/9.2.1/libraries/RServer/RevoScaleR/rxLibs/x64/libmkl_gf_lp64.so
sudo cp /opt/microsoft/mlserver/9.2.1/runtime/R/lib/libRlapack.so /opt/microsoft/mlserver/9.2.1/libraries/RServer/RevoScaleR/rxLibs/x64/libRlapack.so
sudo cp /opt/microsoft/mlserver/9.2.1/runtime/R/lib/libmkl_core.so /opt/microsoft/mlserver/9.2.1/libraries/RServer/RevoScaleR/rxLibs/x64/libmkl_core.so

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