Orange Installation Problem

[spgvieira]

Hi! I keep getting the following problem when installing orange through pip on my pc with ubuntu. Any advice?

pip install orange3 Defaulting to user installation because normal site-packages is not writeable Collecting orange3 Using cached Orange3-3.31.1.tar.gz (26.4 MB) Installing build dependencies ... done Getting requirements to build wheel ... error error: subprocess-exited-with-error

Which version ubuntu, which version of Python, which version of pip?

From the output you it appears you do not have numpy or cython installed which are required for building from source. Note that this should be automatically handled as long as you have a sufficiently recent version of pip, which you probably do not. The best solution is to create a separate virtual environment for orange with a more recent pip version (do not try to upgrade the system provided pip):

python -m venv ~/.envs/orange3
source ~/.envs/orange3/bin/activate
pip install -U pip
pip install orange3

numpy 1.22.3 Cython 0.29.28 pip 22.0.4 Description: Ubuntu 20.04.4 LTS These are the versions the error keeps happening in the virtual environement

A lot of time has passed and we have not responded. In the meantime, there have been several new versions of Orange so the problem may have been resolved. @spgvieira, are you still interested and can you please try again?
