Problem running pysph test and pysph examples

[Riana Hary RANJALAHY ANDRIAMANANA]

Hello PySPH-users,

I was able to install 'pysph 1.0b2.dev0'

but 

1) running 'pysph test' > nothing happen (ends with new prompt)

2) running 'pysph run' > shows list of all cases examples and ask for choice but I could not enter a number, it immediately ends with new prompt

3) running 'pysph run elliptical_drop' > shows the descriptions of the case example then nothing happen (ends with new prompt)

4) navigating to one of the examples (let's say 'example.py') and running 'python example.py' > runs 'example.py' and generates output files with HDF5 files, but I could not run 'pysph view' (ends with new prompt)

*here: 'nothing happen' means nothing, not even an error or warning, just ends with new prompt

Can you guys help? (same case for 'pysph 1.0b1', I want to run SWE in pysph)

thank you!
