Exception in thread "main" java.lang.UnsatisfiedLinkError: no jniopenblas_nolapack in java.library.path

[dongdongunique]

Describe the bug When I used the OLS in the smile.regression, the compiler shows "Exception in thread "main" java.lang.UnsatisfiedLinkError: no jniopenblas_nolapack in java.library.path"

Here is the code: Table data=Table.read().csv("processed.csv");
data.removeColumns("city"); LinearModel osl=OLS.fit(Formula.lhs("price"), data.smile().toDataFrame());

where city is a string column, so I throw it away;

I used java 17 on the windows and vscode. The version of smile is 2.6.0

You miss BLAS/LAPACK on your system. The easiest way is to add smile-mkl as a dependency.

[dongdongunique]

However, when I add smile-mkl dependency to the maven, it shows a new error:

"The container 'Maven Dependencies' references non existing library 'C:\Users\dongdongunique.m2\repository\org\bytedeco\mkl\2020.3-1.5.4\mkl-2020.3-1.5.4-linux-x86_64.jar'"

but my system is windows, I do not know how to solve this problem .

[haifengl]

try these dependencies.

"org.bytedeco" % "javacpp"   % "1.5.7"        classifier "windows-x86_64",
"org.bytedeco" % "openblas"  % "0.3.19-1.5.7" classifier "windows-x86_64",
"org.bytedeco" % "arpack-ng" % "3.8.0-1.5.7"  classifier "windows-x86_64"

You may need to remove smile-mkl.

[dongdongunique]

:'( But other problems arises:

I guess that you use 2.6. So try this version.

  "org.bytedeco" % "arpack-ng" % "3.7.0-1.5.4"  classifier "windows-x86_64" classifier "",
  "org.bytedeco" % "openblas"  % "0.3.10-1.5.4"  classifier "windows-x86_64",
  "org.bytedeco" % "javacpp"   % "1.5.4"        classifier "windows-x86_64"

If it still doesn't work, I guess something wrong with your system. I have no issues on windows.

M2Eclipse is known to have many issues. Please try with Maven instead. Others build tools like Gradle and sbt work fine too.
