AttributeError: module 'ChebTools' has no attribute 'generate_Chebyshev_expansion' #25

Closed OrbitalMechanic closed 3 years ago

OrbitalMechanic commented 4 years ago

I'm attempting to run the following example to test my installation of ChebTools on a Mac Pro (2019) running Mac OS X ver. 10.15.4 (Catalina) using the Anaconda distribution of Python ver. 3.7.6.

#!/Users/user/opt/anaconda3/bin/python
import scipy.special
import ChebTools
import numpy as np
import matplotlib.pyplot as plt
# Only keep the roots that are in [-1,1] in scaled coordinates
only_in_domain = True
# The 0-th Bessel function (for code concision)
def J0(x): return scipy.special.jn(0,x)
# Make a 200-th order expansion of the 0-th Bessel function in [0,30]
f = ChebTools.generate_Chebyshev_expansion(200, J0, 0, 30)
# Roots of the function
rts = f.real_roots(only_in_domain)
# Extrema of the function (roots of the derivative, where dy/dx =0)
extrema = f.deriv(1).real_roots(only_in_domain)

When I attempt to run this example, I get the following message:

(base) user@Samuels-Mac-Pro ~ % python ChebTools-ex.py
Traceback (most recent call last):
  File "ChebTools-ex.py", line 11, in <module>

AttributeError: module 'ChebTools' has no attribute 'generate_Chebyshev_expansion'

Is there something additional I need to install over and above the CMake build instructions?

Please advise.

Hi Sam!

How did you install ChebTools? Are you trying to run from the root folder of the source? If so, try from somewhere else, python can get confused about which folder to load from when you start at the root of the repo.

Generally, it is a bad idea to add the shebang to python scripts; let your environment manager (virtualenv, conda, etc.) figure out where to find things. Otherwise, you can introduce all manner of creative issues, which might be what is going on here.

If none of the above applies, then this would be helpful for debugging (first prints where it is installed, second all the methods that are available in the library)

python -c "import ChebTools; print(ChebTools.__file__, dir(ChebTools))"
OrbitalMechanic commented 4 years ago

Thank you for responding to my post. I installed ChebTools using Cmake as follows:

git clone --recursive --shallow-submodules https://github.com/usnistgov/ChebTools
cd ChebTools
mkdir build
cd build
cmake ..
cmake --build .

I run the example outside of the root folder where ChebTools was built both with and without the shebang line with no difference in the results. I ran a few runs using the command python -c "import ChebTools; print(ChebTools.__file__, dir(ChebTools))" resulting in:

  1. Running from my home directory, /Users/user

I'm pointing out the files in the build subdirectory, because I haven't found any ChebTools components in the subdirectory /Users/user/opt/anaconda3/lib/python3.7/site-packages.

Hope this helps.

ianhbell commented 4 years ago

Hi Sam, if you indeed only want the python interface, then you should follow the pip+git instructions: https://github.com/usnistgov/ChebTools#to-install-in-one-line-from-github-easiest

If you really do want the C++ interface, then you need to figure out how to work with cmake.

I'm sure we can get this working! But you have some odd things going on in your setup, so I wonder what went on.

OrbitalMechanic commented 4 years ago

Ian,

Thank you for getting back to me. I took your advice and tried to build the python interface using the pip+git instruction and that build failed. It appears to be failing to find the omp.h header file, yet I do have OpenMP installed. This is why I tried to build ChebTools using cmake.

Attached to this note is a file containing the results from my attempt at building ChebTools using the pip+git instruction. Should you see something in the listing that might steer me in the right direction, please let me know. Otherwise, I'll have to bone up on cmake to make it work for me.

Sam Dupree.

ianhbell commented 4 years ago

I'll try to compile from one of my mac minis tomorrow, maybe that will shed some light. Are you using g++ from homebrew?

OrbitalMechanic commented 4 years ago

I can use g++ from homebrew if I go thorough cmake and explicitly point to it and to gcc. When I go through the pip+git command clang++ and clang through Xcode is used.

ianhbell commented 4 years ago

Good point - the pip+git solution is going to use your system defaults, which for many cases (albeit often not on OSX) is the right solution.

OSX is probably the platform where I have had the most difficulty getting things to work reliably in general with compiler toolchains.

OrbitalMechanic commented 4 years ago

Is the pip+git solution driven by a Makefile that can be edited so as to point to g++ and/or gcc?

The bad news is that the code hangs:

I'm getting all kinds of weird behaviors on OS X that I haven't seen before. I think it has to do with the Frankenstein clang/g++ incompatibilities.

ibell commented 4 years ago

The binder instance is still working fine, so I think the problem is something about the OS X stuff: https://hub.gke.mybinder.org/user/usnistgov-chebtools-bfhlcst1/notebooks/BattlesTrefethen.ipynb

I repeated what you had done below. I found that I had to run the command git submodule update --init  to installl the pybind11 submodules. After doing that, I run the command CC=gcc-9 CXX=g++-9 python setup.py install, and ChebTools installed successfully. However, like you the ChebTools example hanged.

Any suggestions?

I have very little idea what is going on here.... I tried to upgrade pybind11 to version 2.5, and that yields non-hanging code, but wrong results. There's a bug somewhere, and I wonder if it is a binary incompatibility between the compiler used to build python (Xcode) and the compiler used to build the extension (g++). When I run on other systems without this sort of a mismatch (windows, linux), the library "just works".

So my idea is to patch the cmake things for Xcode to help it find the include folder for the omp.h header (probably the right solution). How comfortable are you with CMake? I'm already a few hours into this problem today, and I don't think I can devote much time for at least a few days to get this working.

OrbitalMechanic commented 4 years ago

When it comes to cmake, I am a novice, but I'm not afraid of hacking my way through it. The trick is knowing the parameters to set, the prerequisites and which options go into which slots.

only_in_domain = True
# The 0-th Bessel function (for code concision)

# Make a 200-th order expansion of the 0-th Bessel function in [0,30]
f = ChebTools.generate_Chebyshev_expansion(200, J0, 0, 30)
# Roots of the function
rts = f.real_roots(only_in_domain)
# Extrema of the function (roots of the derivative, where dy/dx =0)
extrema = f.deriv(1).real_roots(only_in_domain)

For whatever reason the code appearings to hanging in the function call

ChebTools.generate_Chebyshev_expansion(200, J0, 0, 30)

In placing print statements before and after the call, one observes the execution transferring control to the function, but it never returns.

I had gotten things to work on my side, and now I wonder whether bumping pybind11 to version 2.5.0 was part of why. Let me bump that again, and let you take another crack at it.

Just tried the new commit. It now works. I was able to install ChebTools successfully, and when running the example in the README.md file, the example no longer hangs. :-)

Thank you for all your help in getting ChebTools up and running. I really appreciate it.

Great to hear! Purely out of curiosity, what are you using ChebTools for?

First let me say thank you for all your help in getting ChebTools up and running on my Mac. To answer your question as to using ChebTools, I'm  looking into tools for Chebyshev interpolation for planetary ephemerides in Python.

It was my pleasure, and thank you for reporting the issue

I'm pleased that I can contribute to the scientific endeavor in my small part.

FWIW, numpy can now do much of what ChebTools can, check out their Chebyshev polynomial module: https://numpy.org/devdocs/reference/generated/numpy.polynomial.chebyshev.Chebyshev.html . Their documentation for Chebyshev expansions are sparse, to put it kindly.
