M2 and M3 installation issues.

[joshbmat]

We have problems installing the latest FEW master branch on both M2 and M3 machines.

We encounter two problems that seem to be distinct from the M1 installation issue #95 . The first one is easy work around. The second one is problematic.

The first problem is the few.version is not found (test 1):

---------------------------------------------------------------------------
ModuleNotFoundError                       Traceback (most recent call last)
Cell In[5], line 8
      5 get_ipython().run_line_magic('matplotlib', 'inline')
      6 import numpy as np
----> 8 from few.trajectory.inspiral import EMRIInspiral
      9 from few.amplitude.romannet import RomanAmplitude
     10 from few.amplitude.interp2dcubicspline import Interp2DAmplitude

File ~/FastEMRIWaveforms/few/__init__.py:1
----> 1 from few._version import __version__

ModuleNotFoundError: No module named 'few._version'

We get around this by commenting out the only line in ' init.py'.

The second problem is pyInspiral not compiling (subsequent tests):

---------------------------------------------------------------------------
ModuleNotFoundError                       Traceback (most recent call last)
Cell In[6], line 8
      5 get_ipython().run_line_magic('matplotlib', 'inline')
      6 import numpy as np
----> 8 from few.trajectory.inspiral import EMRIInspiral
      9 from few.amplitude.romannet import RomanAmplitude
     10 from few.amplitude.interp2dcubicspline import Interp2DAmplitude

File ~/FastEMRIWaveforms/few/trajectory/inspiral.py:28
     25 from scipy.interpolate import CubicSpline
     27 # Cython/C++ imports
---> 28 from pyInspiral import pyInspiralGenerator
     30 # Python imports
     31 from few.utils.baseclasses import TrajectoryBase

ModuleNotFoundError: No module named 'pyInspiral'

This was highlighted in issue #85 but the issue was seemingly assumed to be the same as issue #81 and was closed. We tried again using the older commit 0c52a1c tagged as resolving issue #81 and the commits either side but ran into the same problems. It's possible that issue #85 was never fixed by the subsequent commits?

I have the same problems too, on ubuntu 23.10.

Me too

I encountered both of these issues while installing the package on my personal computer (MacBook with Intel chip).

As mentioned in the comments in issue #94, I fixed the first issue as follows. After cloning the Github repo from the source, but before running 'bash install.sh', I moved the prebuild.py file into its parent folder (e.g., running 'mv ./scripts/prebuild.py ./' while in the './FastEMRIWaveforms' directory), and then ran 'prebuild.py'. After doing this, I could build the wheel successfully.

I then encountered the second issue about there being no 'pyInspiral' module when running the import statements in cell 1 the examples notebook in a new jupyter notebook saved in the './FastEMRIWaveforms' directory. However, I only got these errors when I did not launch the notebook inside the 'few_env' environment in the terminal. That is, I was able to fix the second error message by running 'jupyter notebook' inside the 'few_env' environment in the terminal, and then running the same code from the browser that is launched by that command.

Since I did not encounter these problems on an M-chip Mac, I'm not sure if the root cause of the error messages on my computer is the same for the OP, but I thought I'd mention how I fixed the same error messages just in case it helps.
