Numba not installing

[JoelGodin]

Tried to install 0.3.48 and am getting this error:

I hit install, it installed something (from that popup) and then tried install numba and it turned blue for a moment, and then nothing. Still says numba has to be installed.
I used to have Xcode, but recently had a hard drive crash and did a new install on an SSD.
Now I can't install Xcode because is says I need 10.15 or newer.
I have 10.13 and can't install any newer macOS's.
Do I really need Xcode to install numba?

A clarification: I did hit install so I'm thinking it did install the dev tools. But still no numba install is happening.

[JoelGodin]

Looks like dev tools is installed:

Just read that is it mostly for Reaction-Diffusion which I don't use, so no urgency on my part.

[alessandro-zomparelli]

Hi @JoelGodin , yes, I can confirm that it is currently used only for the Reaction-Diffusion.
Unfortunately, I don't know the macOS, and I really don't know how to fix that.
@s-leger you helped me with that before, any chance that you know what is happening? Thanks

As far as i can tell, a precompiled version of numba for python 3.7 may not be available for macOS, so the pip installer download source and must compile on the fly.
Pip run using "--only-binary all" option by default, meaning it should only download binary when available and may fallback to source when not available.

[alessandro-zomparelli]

Hi @s-leger thanks :-) Do you have any possible solution to suggest?

[s-leger]

Pip class should be verbose enougth to provide a reason for failure to install pre-compiled version, maybe a missing dep issue (as by default it does not try to solve such deps --no-deps argument)
Any console log of failed setup may help to narrow down the issue on macOS - maybe missing llvmlite 0.34.*

No deps argument is important as such package may require numpy as dep and is likely to break blender's numpy by overriding it.

I am seeing this:  nw_path_close_fd Failed to close guarded necp fd 6 [9: Bad file descriptor]

open blender and from a console, run (assuming tissue folder is "tissue-master")

from tissue-master.utils_pip import Pip
Pip.install("numba") 

You should see a brunch of pip related lines on the console.

[JoelGodin]

I got this:

>> from tissue-b290-dev0.3.48.utils_pip import Pip

File "<blender_console>", line 1 from tissue-b290-dev0.3.48.utils_pip import Pip ^ SyntaxError: invalid syntax

Ok,
pay attention at removing every "." in the folder name, could also be an issue for blender - this is not allowed by python - !

[JoelGodin]

Like this:

[s-leger]

Rename the folder itself, removing dot in folder name.
then

from your_new_folder_name.utils_pip import Pip

[JoelGodin]

Screen shot here:

[JoelGodin]

oops, I see what I did. Hold on.

[JoelGodin]

Okay, I get this

from tissueb290dev0348.utils_pip import Pip
Traceback (most recent call last):
File "<blender_console>", line 1, in
ModuleNotFoundError: No module named 'tissueb290dev0348'

[s-leger]

When you setup on macOS it does unzip into (assuming you are using default settings to setup your addons)
/Users/$USER/Library/Application Support/Blender/2.91/scripts/addons/tissue-xxx
You must use that folder name for the command, and ensure the folder name does not contains any "." in the between.

[JoelGodin]

Get this

[s-leger]

hmm looks like it also did not like the "-" in the names.

[JoelGodin]

Okay, removed, recompressed, went okay, this from second command:

from tissueb290dev.utils_pip import Pip
Pip.install("numba")

Ok, may miss llvmlite
Try
Pip.install("llvmlite")
and then the numba setup.

[JoelGodin]

Hmm, with such "usefull" status report will be pretty hard to figure what the issue realy is.
As far as i can tell there is no "wheel" available and it still expect xcode in order to build.
Maybe you should ask on numba mailing list.

[JoelGodin]

ok, thanks for your help on this.

[JoelGodin]

@s-leger Just wanted to ask first, "As far as i can tell, a precompiled version of numba for python 3.7 may not be available for macOS, so the pip installer download source and must compile on the fly."
I have python 2.7.16
Would that be the issue?

[s-leger]

Blender should use her own python interpreter.
You should see the version number in the blender's python console.
Looks like the downloaded file is not a wheel (?) and require compilation.

Numba require

• Python versions: 3.6-3.8
• llvmlite 0.34.*
• NumPy >=1.15 (can build with 1.11 for ABI compatibility)
  Optionally:
• Scipy >=1.0.0 (for numpy.linalg support)

[JoelGodin]

I see.
I'm going to try and download Xcode first.
I had a hard drive crash and this is a new drive.
I had numba working on my last hard drive. It had Xcode installed.
Update: Installing Xcode did not change anything.
