Issue when generating custom dataset.

[gupta-anmol99]

When I try to run the bash script for xml converter, I encounter a problem with qhull and the corresponding xml file is not generated.

QH6154 qhull precision error: initial facet 1 is coplanar with the interior point
ERRONEOUS FACET:
- f1
    - flags: bottom simplicial flipped
    - normal:         0        0       -1
    - offset:       0.52
    - vertices: p2(v2) p1(v1) p0(v0)
    - neighboring facets: f2 f3 f4

While executing:  | qhull Qt
Options selected for Qhull 2012.1 2012/02/18:
  run-id 1640577472  Qtriangulate  _pre-merge  _zero-centrum  _max-width 1.1

  _wide-facet 1e-14

precision problems (corrected unless 'Q0' or an error)
      2 flipped facets
      2 degenerate hyperplanes recomputed with gaussian elimination
      4 nearly singular or axis-parallel hyperplanes
      2 zero divisors during back substitute
      3 zero divisors during gaussian elimination

The input to qhull appears to be less than 3 dimensional, or a
computation has overflowed.
