Hi all,

I am trying to run another lab’s script on my laptop, and everything works but the DlgFromDict() function (or any Dlg function). In other words, if I comment out these lines the actual experiment works just fine.

```auto
 dlg = gui.DlgFromDict(expInfo, title='Audio-visual Flashlag', fixed=['dateStr'])
 if dlg.OK:
     toFile('lastParams.pickle', expInfo) # save params to file for next time
 else:
     core.quit() # the user hit cancel so exit

```

If I do not comment these lines (and a few more that reference them), a brief psychopy window opens before crashing almost immediately. I have tried running the script from both PyCharm and from the terminal and I get the same error message. Details posted below. Any help would be greatly appreciated.

**My Versions:**  
OSX: 10.14.2 (Mojave)  
PsychoPy 1.90.3  
Conda 4.6.8  
Python 2.7.15 (running in its own conda environment because it’s python 2)

_Note_: I also have a separate environment for Psychopy3 and the DlgFromDict() function works perfectly. Does this suggest it’s a package issue? How would I narrow which one?

**The full error message:**

I think you’re missing PyQt or have a broken version of it or something. By default the gui library uses QTgui, and I don’t see PyQt in the reqs list here. If it’s always crashing when trying to make a dialog, it’s either that Qt is crashing, or that it’s trying to use something other than Qt and that’s crashing. I honestly don’t know what the alternative is for the QT-based GUI.

Thanks! Installing PyQt fixed the issue - everything works great now.
