Windows unable to install. It keeps asking to install numpy even though its already installed.

[rohitkrishna094]

I am using windows 10 and Python 3.12.0 and I created a new folder and ran the below commands as Administrator in a command prompt.

python -m venv venv
venv\Scripts\activate
pip install numpy # success
pip install aeneas # failed

Error

Why am I getting an error saying that "You must install numpy before installing aeneas"? It makes no sense because according to aeneas documentation itself I ran pip install numpy successfully before running pip install aeneas

I'm facing the same issue

[vantoan19]

It just failed recently, before that it worked normally

I think this is related to numpy deprecating distutils, which is used within setup.py for installing aeneas.

Inside setip.py one reads:

try:
    from numpy import get_include
    from numpy.distutils import misc_util
except ImportError:
    print("[ERRO] You must install numpy before installing aeneas")
    print("[INFO] Try the following command:")
    print("[INFO] $ sudo pip install numpy")
    sys.exit(1)

About distutils:

numpy.distutils is deprecated, and will be removed for Python >= 3.12

The issue is not exclusive to Windows. I had the same problem o Ubuntu.

Have you tried downgrade your python version? I was able to install aeneas on python 3.5.10. On python 3.10.1 I cannot pip install aeneas, since I hit the error described on this issue.

However, if I clone the repo, I can execute python -m aeneas.tools.execute_task from the command line (on python 3.10.1). The problem seems to be only on the tooling used for packaging the project.

same error, i change to python3.10 and fix it

If you still have issues with python version < 3.12, install wheel package before aeneas. That helped for me

I've solved this problem changing lines 188 and thereon in setup.py by excluding numpy misc_util as reported in #306 to:

# try importing numpy: if it fails, warn user and exit
try:
    from numpy import get_include
    # from numpy.distutils import misc_util
except ImportError:
    print("[ERRO] You must install numpy before installing aeneas")
    print("[INFO] Try the following command:")
    print("[INFO] $ sudo pip install numpy")
    sys.exit(1)

# to compile cdtw and cmfcc, we need to include the NumPy dirs
INCLUDE_DIRS = [get_include()]

after this I was able to do

python setup.py build_ext --inplace
python aeneas_check_setup.py

and

python setup.py install

to verify and install aeneas.
