Exception in algorithms when using Parallel Colt #144

Open jjpedreno opened 6 years ago

jjpedreno commented 6 years ago

When developing algorithms, a line of code such as:

IntMatrix1D v = IntFactory1D.dense.make(6,1);

Gives the following exception when executed:


Exception in thread "main" java.lang.NoSuchMethodError: edu.emory.mathcs.utils.ConcurrencyUtils.getThreadsBeginN_1D()I
 at cern.colt.matrix.tint.IntMatrix1D.assign(IntMatrix1D.java:488)
 at cern.colt.matrix.tint.impl.DenseIntMatrix1D.assign(DenseIntMatrix1D.java:440)

This is a known error (among others) of ParallelColt-0.10.1. The fix is to upgrade to version 0.11.4 (available at https://github.com/rwl/ParallelColt/)
