Loading Error about timezonefinder

[jannikmi]

hey jrifai,
at the first glance it looks like the error is related to Numba and its use.
I am not really sure what it is yet, but since you are the first one reporting that error, i guess it has something to do with dependencies...
Sorry for asking this, but have you installed the LLVM compiler?
http://numba.pydata.org/numba-doc/0.26.0/developer/contributing.html#buildenv
I will look further into it when you have.
Greetings

Thanks for your answer.
I installed Numba with conda. Is not enough ?
I tried to install LLVM compiler, but no success for : from timezonefinder import TimezoneFinder

[jannikmi]

I don't know what the problem exaclty is, but i am pretty sure it is a problem with your Numba installation.
Please try uninstalling Numba completely (reverse your conda installation) and then check if timezonefinder works (without numba).
Then install numpy.
Then install llvmlite manually: http://llvmlite.pydata.org/en/latest/install/index.html#building-manually
and reinstall Numba (without conda).
That worked for me.
Hope that helped, but if not please consider looking for similar errors reported by Numba users.

Is your problem fixed?

Hi,
Finally I used an other way to achieve my goal.
Thanks anyway for your avaibility !

Hi, I wanted to second the fact that I am experiencing this issue as well. I am using a Mac OS X El Capitan version 10.11.4

Like MrMinimal64, I installed Numba using conda install Numba before pip installing timezonefinder.
I was unable to import timezonefinder with our without Numba
As for the LLVM compiler, it was already installed.

My terminal output from running "brew info llvm" is:

brew info llvm

==> Caveats
LLVM executables are installed in /usr/local/opt/llvm/bin.
Extra tools are installed in /usr/local/opt/llvm/share/llvm.

This formula is keg-only, which means it was not symlinked into /usr/local.

OS X already provides this software and installing another version in
parallel can cause all kinds of trouble.

If there is anything that you think I'm doing incorrectly, pointers would be greatly appreciated!

First of all, thanks for reporting.
Since I don't know how @jrifai solved the issue after all and I do not know too much about Numba or llvm, I can basically just give you the same advice:

Consider if it is really necessary for you to use the package with Numba. If that's true:

Please try uninstalling Numba completely (reverse your conda installation) and then check if timezonefinder works (without numba).
(install numpy)
Then install llvmlite manually: http://llvmlite.pydata.org/en/latest/install/index.html#building-manually
and reinstall Numba (I did it without conda).

On https://github.com/numba/numba it says the dependency is llvmlite so maybe your llvm version is not sufficient.

Please let me know if and how you solved the issue. Thanks

@MrMinimal64: No problem.
I tried conda uninstall numba again, and timezonefinder magically worked. I'm not sure why it worked this time but not the first time I imported timezonefinder without Numba.

Thanks for pointing me in the right direction!

[jannikmi]

Ok, great. But could you please check if you are using Numba now:

from timezonefinder import TimezoneFinder
print(TimezoneFinder.using_numba())

[timothyb0912]

Sure thing: I used the two commands you posted and got False.

[jannikmi]

So then that means, your timezonefinder works because you are not using it with numba. But you don't have to, it's just slower.
