to-matrix under version 1.4.1

[Fernando Saldanha]

I noticed that the following code:

(def ret-ds (incanter.io/read-dataset "C:/Dropbox/Data/ClojureData.csv" :header true))

(def ret-mat (to-matrix ret-ds))

fails under version 1.4.1 of incanter io

with the following message:

NoSuchMethodError edu.emory.mathcs.utils.ConcurrencyUtils.getThreadsBeginN_2D()I  cern.colt.matrix.tdouble.impl.DenseColumnDoubleMatrix2D.assign (DenseColumnDoubleMatrix2D.java:661)

It works under version 1.3.0. Any suggestions?

Thanks.

Hi

That's very strange - it works on my mac os x, so maybe it's windows-specific problem of parallel colt? do you see parallelcolt-0.10.0.jar in the classpath that is printed by 'lein classpath' command?

I can't reproduce the problem here (Windows 8, Java 1.7.0_21, with Incanter 1.4.1 checked out). The incanter-io test cases all pass without any problems.

Thanks,

I had similar error when tried to run some incanter code on server. Server was tomcat or jboss (I don't remember exactly). Issue was fixed by switching to different version of a server. It seems that server was using some other version of emory utilities. So the problem might be that some other libs using it's own version of emory utilites. You can check where ConcurrenctyUtils class is loaded from by using following snippet:

(-> edu.emory.mathcs.utils.ConcurrencyUtils .getProtectionDomain .getCodeSource .getLocation)

It gives me (at my machine) following:

#<URL file:/home/nikelandjelo/.m2/repository/net/sourceforge/parallelcolt/parallelcolt/0.10.0/parallelcolt-0.10.0.jar>

So I suppose that correct lib is parallelcolt-0.10.0
