1)starting with conda list1 : 2)after executing: conda create --name new_hal -c conda-forge -c threeml numpy scipy matplotlib ipython numba reproject "astromodels>=2" "threeml>=2" root

( packages in list 2)

3) scipy has a conflict with another/other packages: "ValueError: source code string cannot contain null bytes"

4) also after a full installation import HAL fails due to scipy problem

Hi Amid!

When/how are you getting the error message "ValueError: source code string cannot contain null bytes" ?

Amidn commented 3 years ago

Hi Henrike,

First I got this error after a full installation: "from hawc_hal import HAL, HealpixConeROI, HealpixMapROI" (in this step: "from scipy.integrate import trapz")

then I started to reinstall from the beginning and I checked the scipy step by step. I see "import scipy" is not possible (if it helps, I can share my screen) Regards Amid

Hi Amid!

I cannot reproduce this error with MacOS catalina/XCode 12.0.1. I do not believe the issue related to hawc_hal.

Googling shows that "ValueError: source code string cannot contain null bytes" indicates the presence of a null byte (\x0) somewhere in your source code.

You can find some instructions to remove these if you check stack overflow.

I have no idea why/how these null bytes appear, like I said I cannot reproduce it. If it persists for other users of big sur/newer versions of XCode, you might want to report it to apple.

Cheers Henrike

Thank you I hope this is not related to the Big Sur Regards

I confirm that on Mac Mojave, Xcode 10.3, this problem did not occur (So it is related to version conflict )

henrikef commented 3 years ago

Closing this as it's not related to hawc_hal. Good luck!
