AttributeError: module 'numpy' has no attribute 'asscalar'

[isaacovercast]

What version of toyplot do you have installed? conda list | grep toyplot. It looks like you're using an older version as these are both errors inside of toyplot.

The 'asscalar' error is coming from toyplot and this has been fixed already (sandialabs/toyplot#205) , so make sure your toyplot version is > 1.0.2.

The Collections.Sequence error is also fixed in the most recent versions of toyplot (sandialabs/toyplot#202). Please update your toyplot version and try again and let me know how it goes.

[LalitaSimpson]

Thanks. Yes i had an older version of toyplot. I've now done a fresh install of ipyrad in a clean environment and have got past that error and onto another... Im still using the STRUCTURE jupyter notebook and everything seems ok now up till the "Analyze results: Barplots" step. There seems to be some kind of an issue with clumpp? I do have clumpp installed v 1.1.2. Any advice is much appreciated. many thanks:

I will guess that you are working on a mac with an M1 processor? The clumpp binary is only available at the moment for intel macs, so i will have to take a closer look to figure out how to fix this. Let me know if what I think about your mac processor is correct.

[LalitaSimpson]

Hi Isaac, I am on a mac but i have one of the last with an intel processor as I wanted to avoid compatibility issues with the M processors. I am on a macbook pro, 2 GHz Quad-Core Intel Core i5 processor, 16BG memory. Any other ideas? Thanks.

[isaacovercast]

Can you try this and show me the result?

file /Users/Lalita/miniconda3/envs/ipyrad1/bin/CLUMPP

Mine works and mine looks like this: Mach-O executable i386

Can you also show results for this? sysctl -a | grep brand? Mine looks like this

machdep.cpu.brand_string: Intel(R) Xeon(R) CPU           E5645  @ 2.40GHz
machdep.cpu.brand: 0

[alexkrohn]

Hi @isaacovercast. I too am running into problems using CLUMPP with an M2 silicon chip. I also tried installing Rosetta 2 and specifying the 64 bit architecture, as suggested here. No effect.

Hi Alex,

Well, it looks like Rosetta doesn't support 32bit binaries, so that's going to be hard to work around. I will make a new issue to build and push a 64bit binary, but it won't happen any time soon, sorry to say. Best workaround now is to find an intel box unfortunately.

[alexkrohn]

Thanks for making the issue. I figured it'd be low priority, no worries at all.

At the very least I can run Structure on the fast M2 chips with the parallelization that ipa offers, then take the results and reload them on a computer with intel-based chips to do the CLUMPP functions (as here).
