numexpr3 lookup.pkl cannot be loaded after bundling with pyinstaller

[danielhrisca]

Hello,

I've tried to bundle an application that uses numexpr3 using PyInstaller, but I get to an error at this line https://github.com/pydata/numexpr/blob/numexpr-3.0/numexpr3/ne3compiler.py#L54

This is the error traceback:

Traceback (most recent call last):

basically that paths from the traceback are the ones from the virtual env used to run Pyinstaller, but the bundled application is found somewhere else on the disk.

Is is possible to use the current file location to determine the pkl path instead of using the inspect module?

I recall there was some specific reason for doing this and now I cannot remember why.
