problem with installation

[tk575]

Hello, I followed the step-by-step described for installation, however when I use the command: python3 atrack.py fits_dir "the following message appears: Python can not import alipy. Make sure alipy is installed". The problem is that I have alipy installed correctly. could you help me with this problem? Is there any documentation available? Thank you!

Hi @tk575,

Could you please give the following commands in terminal,

$ python3

import alipy
from alipy import pysex

Then, please send us the output.

Hello, thank you for your response.

The output is:

Python 3.6.8 |Anaconda, Inc.| (default, Dec 30 2018, 01:22:34)

Type "help", "copyright", "credits" or "license" for more information.

import alipy
from alipy import pysex
Traceback (most recent call last):

ImportError: cannot import name 'pysex'

It seems that you do not have pysex module. Maybe you have installed alipy package from another source. Maybe you should install alipy package again?

Download and install astroasciidata:

git clone https://github.com/japs/astroasciidata.git
cd astroasciidata
sudo python3 setup.py install

Download and install Alipy:

git clone https://github.com/akdeniz-uzay/alipy.git
cd alipy
sudo python3 setup.py install

Hi, I reinstalled the packages, following their recommendations and it worked! Another question is whether there is any way to detect only one object of interest (an asteroid for example) by specifying the coordinates (x, y) in the first image and obtaining the (x, y) coordinates for the other images, reducing the Computational time?...

Hi @tk575,

Unfortunately, it is not possible with the A-Track. Our primary purpose is to detect unknown moving objects without any human intervention. Maybe you should check @rankinstudio's Asteroid_Detector.
