Importing the multiarray numpy extension module failed

[IT-Berater]

Hi,

i update to python3 and install numpy-1.15.4-cp35-cp35m-linux_armv6l.whl on my headless Raspberry Pi (without X-Server) and install unicornhathd.

Thist is the error:

python3 ./tracker.py 52 9 Traceback (most recent call last): File "/usr/local/lib/python3.5/dist-packages/numpy/core/init.py", line 16, in from . import multiarray ImportError: libf77blas.so.3: cannot open shared object file: No such file or directory

During handling of the above exception, another exception occurred:

Traceback (most recent call last): File "./tracker.py", line 5, in import numpy as np File "/usr/local/lib/python3.5/dist-packages/numpy/init.py", line 142, in from . import add_newdocs File "/usr/local/lib/python3.5/dist-packages/numpy/add_newdocs.py", line 13, in from numpy.lib import add_newdoc File "/usr/local/lib/python3.5/dist-packages/numpy/lib/init.py", line 8, in from .type_check import * File "/usr/local/lib/python3.5/dist-packages/numpy/lib/type_check.py", line 11, in import numpy.core.numeric as _nx File "/usr/local/lib/python3.5/dist-packages/numpy/core/init.py", line 26, in raise ImportError(msg) ImportError: Importing the multiarray numpy extension module failed. Most likely you are trying to import a failed build of numpy. If you're working with a numpy git repo, try git clean -xdf (removes all files not under version control). Otherwise reinstall numpy.

Original error was: libf77blas.so.3: cannot open shared object file: No such file or directory

Ok, i fix the error.

It works for 3 Airplane, and then Error ...FileNotFoundError

To clarify, do you have a UnicornHatHD and have you installed the associated python module to manipulate it? Or are you just trying to use it without the UnicornHat display?

[IT-Berater]

I have no UnicornHat display and i installed only the UnicornHadHD modul, because it is necessary for the script :-(

You need the screen really. I am working on an emulator so that you can use pygame instead.
