External package problem from Vizard Package Manager

Dear Forum,

Has anyone had problems using packaging that has been downloaded and installed via the package manager in Vizard?

I recently installed the pykalman package and when I try to run a very simple script to see if the package is working properly (just importing viz and pykalman modules before calling viz.go() ) and I get this error message:

** Loading
Traceback (most recent call last):
  File "<string>", line 11, in <module>
  File "C:\SWIG_EXAMPLE\HapticMaster\HapticMasterEx\tpose_reset_demo\", line 2, in <module>
    import pykalman
  File "C:\Program Files (x86)\WorldViz\Vizard4.10\bin\lib\site-packages\pykalman\", line 10, in <module>
    from .standard import KalmanFilter
  File "C:\Program Files (x86)\WorldViz\Vizard4.10\bin\lib\site-packages\pykalman\", line 12, in <module>
    from scipy import linalg
  File "C:\Program Files (x86)\WorldViz\Vizard4.10\bin\lib\site-packages\scipy\linalg\", line 159, in <module>
    from .misc import *
  File "C:\Program Files (x86)\WorldViz\Vizard4.10\bin\lib\site-packages\scipy\linalg\", line 5, in <module>
    from . import blas
  File "C:\Program Files (x86)\WorldViz\Vizard4.10\bin\lib\site-packages\scipy\linalg\", line 145, in <module>
    from scipy.linalg import _fblas
ImportError: DLL load failed: The specified module could not be found.
** Load Time: 0.15 seconds
I have read before on this forum that I might have to manually install the packages. I have tried that before with no luck. Also by installing via the package manager the dependencies that pykalman requires (numpy, scipy, Sphinx, numpydoc, nose) which I have also have installed. It does seem to be a problem with scipy, so Iíll try to sort that out.

Has anyone else come across this before?

Please forget the above post. I have just solved the problem! There was a problem with the SciPy package and I resorted to a full package from the sourceforge site and everything works fine now!
