error with floats

I recently recompiled Tractor in Python 3.7.
I realized that it crashes when I try to create a point source (using PointSource(pos,flux) ), which it did not do when I was running the same code on my other computer that has python 3.6 installed.
The error (a cast error) is attached below.
I (think) I was able to fix it by changing line 52 in “psf.py” from
mp_fourier.lanczos_shift_3f(img, outimg, dx, dy, work_corr7f)
To
mp_fourier.lanczos_shift_3f(img.astype(np.float32), outimg, dx, dy, work_corr7f)
Just letting you know (and maybe you even have a better solution for this or you know where else this problem can make Tractor crash).
