arahlin / qpoint Goto Github PK

I am trying to integrate qpoint into a Docker container. In our base:

• python is python2, not python3.
• numpy and astropy will be installed and ready in the python3 system, not python2.

The problem is that src/make_iers_bulletin_a_dot_c.py is invoked with python, and I need it to be invoked with python3.

Ideally (?) setup.py would cause that script to be launched with the same interpreter that was used to launch setup.py. Alternately, if src/Makefile used the $(PYTHON) make variable instead of python that would be good enough for my purposes!

build_log.txt

Sort of a two-part issue here...

(a) The docs for azel2bore say the argument vectors need to be arrays with the same shape... but in fact broadcasting is supported. Would be great if this were officially documented.

(b) The broadcasting triggers a numpy warning if there's a mix of scalars and arrays. For example, this code:

import qpoint
import numpy as np

qp = qpoint.QPoint()
az, el, t = 90., 50., 1570000000.

print('test 1')
Q = qp.azel2bore(az, el, None, None,
                 lon=160., lat=-22., ctime=t)

print('test 2')
az, el, t = [np.array([_x]) for _x in [az,el,t]]
Q = qp.azel2bore(az, el, None, None,
                 lon=160., lat=-22., ctime=t)
print('done')

yields this output:

test 1
test 2
