Similarly:

python rF2data.py 
Traceback (most recent call last):
  File "rF2data.py", line 718, in <module>
    info = SimInfo()
  File "rF2data.py", line 697, in __init__
    self._rf2_tele = mmap.mmap(0, ctypes.sizeof(rF2Telemetry), "$rFactor2SMMP_Telemetry$")
TypeError: an integer is required (got type str)

    self.close()
  File "rF2data.py", line 707, in close
    self._rf2_tele.close()
AttributeError: 'SimInfo' object has no attribute '_rf2_tele'

It's not clear why or what's wrong.

The above was running on Linux, so it's entirely possible that's the problem. Although rF2 does run on Linux.

Sorry, the notification email was filtered away so I had no idea about this. I can't promise when I'll look at this code again but at least I know it needs attention now.

Hi, if I'm not mistaken, this issue was fixed in those two PR by berarma s-victor#1 & s-victor#3 , which is by separating windows & linux to each of their own mmap parameters (and 2nd PR creates mmap files required under linux), since two system using two different mmap), there is further improvements in the following fork used by tinypedal (see rF2MMap class section):

Hope helps.
