ImportError: No module named path

I use pyinstaller 3.1.1, python 2.7.12, OpenOPC 1.3.1

pyinstaller syntax:
pyinstaller.py --onefile toggle_button_openopc.py 

and my script:
import wx
import OpenOPC

class MyForm(wx.Frame):

    def __init__(self):
        wx.Frame.__init__(self, None, wx.ID_ANY, "OpenOPC", 
                                   size=(500,500))
        panel = wx.Panel(self, wx.ID_ANY)
        self.toggleBtn = wx.Button(panel, wx.ID_ANY, "Connect")
        self.toggleBtn.Bind(wx.EVT_BUTTON, self.onToggle)

    def onToggle(self, event):
        btnLabel = self.toggleBtn.GetLabel()
        if btnLabel == "Connect":
            self.toggleBtn.SetLabel("Disconnect")
            print "starting connection..."
            PLC = OpenOPC.client()
            PLC.connect('CoDeSys.OPC.02')
        else:
            print "stop connection..."
            self.toggleBtn.SetLabel("Connect")

if __name__ == "__main__":
    app = wx.App()
    frame = MyForm().Show()
    app.MainLoop()
