Hi,
I am seeing this exception when trying to save a jagged array to a stream:
Index was outside the bounds of the array.
at NumSharp.np.d__109`1.MoveNext()
at NumSharp.np.writeValueJagged(BinaryWriter reader, Array matrix, Int32 bytes, Int32[] shape)
at NumSharp.np.Save(Array array, Stream stream)
I haven't pinpointed the root cause specifically, but it seems that there is some issue with jagged arrays when the outer array has rank 1:
static IEnumerable<T> Enumerate<T>(Array a, int[] dimensions, int pos)
{
if (pos == dimensions.Length - 1)
{
for (int i = 0; i < dimensions[pos]; i++)
yield return (T)a.GetValue(i);
}
else
{
for (int i = 0; i < dimensions[pos]; i++)
foreach (var subArray in Enumerate<T>(a.GetValue(i) as Array, dimensions, pos + 1))
yield return subArray;
}
}
When pos == 0 and dimensions[] has length 0, the else will execute and pos(0) will be out of bounds.
dimensions[] has length 0 from the caller, which passes:
int[] first = shape.Take(shape.Length - 1).ToArray();
so first[] will be an empty array when shape has length 1 (as in, the single dimension of the 1 dimensional outer jagged array).
