First Run Error

[Sagar Patnaik]

Hi

Even though the Expresso window starts-up and the drop down lists for selecting type of data, loading data are working perfectly fine, on selecting the cifar_t1.hdf5 file and pressing Open button, nothing happens. We are supposed to expect a notifiction on successful import and a name of the table in View/Select Table.

I also tried importing a folder of 2 images, but it too doesn't work and in both the cases I get the following on my terminal. Please help.

I am getting the following error on running the command " sh run_expresso.sh " :

I experienced the same problem recently. It is because pyqtgraph has changed the way it deals with images. It now considers float as representation. I will send you updated git patch, and also change the source, if I find it a generic. However, can you tell me which version of ubuntu are you using?
