Getting FDC to work cant install scipy

so has anyone managed to get FDC to run..? whilst running = python3 -m pip install -r requirements.txt
python3 generate_FDC_meshes_z_heights.py json_file 0.1 --filter_noise , Im getting errors such as ModuleNotFoundError: No module named 'scipy' . I did the git clone, and it runs, building the mesh with temp .. any help would be appreciated.

Something appears to be broken on your Pi's Python installation and tbh such errors are stupid to debug.
Worst case you break something else, if you start upgrading or installing stuff.

Scipy needs some Fortran tools, which you might be able to get with one of these commands (according to the internet)

Mietzekatzi•7/2/23, 12:56 PM

But if you tried to run the script on your Windows PC, you'll only need to install Python (from the official website) and do

moderate-tomatoOP•7/2/23, 1:02 PM

thanks, frustrating that gfortran and build-essential are already installed and latest version

Mietzekatzi•7/2/23, 1:03 PM

hmm, further evidence that something is broken ThisIsFine

Mietzekatzi•7/2/23, 1:05 PM

if you run , is the tool found?

moderate-tomatoOP•7/2/23, 1:05 PM

so if i burnt a new image on my sd.. what files from my install would i need to backup, just printer.cfg ?

Mietzekatzi•7/2/23, 1:06 PM

One more thing to try:

moderate-tomatoOP•7/2/23, 1:06 PM

GNU Fortran (Raspbian 10.2.1-6+rpi1) 10.2.1 20210110

Mietzekatzi•7/2/23, 1:07 PM

So it is cleared found

Mietzekatzi•7/2/23, 1:07 PM

Good question, maybe there is documentation on the RatOS homepage.
I'd backup the whole printer_data directory, to be safe

moderate-tomatoOP•7/2/23, 1:08 PM

ok just tried pip install scipy --no-build-isolation

moderate-tomatoOP•7/2/23, 1:08 PM

Mietzekatzi•7/2/23, 1:10 PM

pip install meson-python

moderate-tomatoOP•7/2/23, 1:12 PM

ok just installed that amd now trying the scipy again

Mietzekatzi•7/2/23, 1:12 PM

... with the --no-build-isolation, yes!

moderate-tomatoOP•7/2/23, 1:13 PM

yes with that

moderate-tomatoOP•7/2/23, 1:13 PM

just waiting at the mo

Mietzekatzi•7/2/23, 1:16 PM

another idea: uninstall numpy, then reinstall scipy.

(-> answer with yes)
(will also hopefully also install a compatible version of numpy)

moderate-tomatoOP•7/2/23, 1:18 PM

so close !

I REALLY appreciate your help BTW

Mietzekatzi•7/2/23, 1:18 PM

pip install ninja kek

Mietzekatzi•7/2/23, 1:20 PM

That why i absolute hate compiling things from scratch. At the end you have 900 ancient tools on your PC.

I'm quickly off to wash the car, so I may take longer to respond kek

moderate-tomatoOP•7/2/23, 2:22 PM

Beat me to it. Im just reinstalling Python 3.7 as that is one of the pre-requisites.. dont think it was installed need

moderate-tomatoOP•7/2/23, 2:24 PM

will then try again with the scipy .. this is going to be one messy install at this rate

Mietzekatzi•7/2/23, 2:26 PM

3.9 should have worked too, i'd rather upgrade to newest version 3.11

This isn't a python package now, according to the internet it comes from

moderate-tomatoOP•7/2/23, 3:09 PM

ok installed that, now running scipy, taking forever
