problem installing ASED3

[icamps]

Hello,

I am trying to setting up ASE-ANI in my box with Linux Mint 19.1

When I run the test, I got:
python3 ~/bin/ASE_ANI/examples/ani_quicktest.py van Der Waals correction will be unavailable. Please install ased3 Traceback (most recent call last): File "/home/icamps/bin/ASE_ANI/examples/ani_quicktest.py", line 16, in <module> mol = read('data/water.xyz') File "/usr/lib/python3/dist-packages/ase/io/formats.py", line 428, in read parallel=parallel, **kwargs)) File "/usr/lib/python3/dist-packages/ase/io/formats.py", line 475, in _iread fd = open_with_compression(filename) File "/usr/lib/python3/dist-packages/ase/io/formats.py", line 286, in open_with_compression return open(filename, mode) FileNotFoundError: [Errno 2] No such file or directory: 'data/water.xyz'

But trying to install ASED3, I got then (with python setup.py install):
gfortran: error: build/temp.linux-x86_64-2.7/ased3/_d3params.o: No such file or directory gfortran: error: build/temp.linux-x86_64-2.7/ased3/_d3.o: No such file or directory gfortran: error: build/temp.linux-x86_64-2.7/build/src.linux-x86_64-2.7/ased3/_d3-f2pywrappers2.o: No such file or directory

If I execute python3 setup.py install

I got:
build/src.linux-x86_64-3.6/ased3/_d3module.c:17:10: fatal error: Python.h: No such file or directory #include "Python.h" ^~~~~~~~~~ compilation terminated. build/src.linux-x86_64-3.6/ased3/_d3module.c:17:10: fatal error: Python.h: No such file or directory #include "Python.h" ^~~~~~~~~~ compilation terminated. error: Command "x86_64-linux-gnu-gcc -pthread -DNDEBUG -g -fwrapv -O2 -Wall -g -fstack-protector-strong -Wformat -Werror=format-security -Wdate-time -D_FORTIFY_SOURCE=2 -fPIC -Ibuild/src.linux-x86_64-3.6/build/src.linux-x86_64-3.6/ased3 -I/usr/lib/python3/dist-packages/numpy/core/include -I/usr/include/python3.6m -c build/src.linux-x86_64-3.6/ased3/_d3module.c -o build/temp.linux-x86_64-3.6/build/src.linux-x86_64-3.6/ased3/_d3module.o -MMD -MF build/temp.linux-x86_64-3.6/build/src.linux-x86_64-3.6/ased3/_d3module.o.d" failed with exit status 1

I appreciate any help.

@icamps there are two separate errors. First "file not found" because in example ani_quicktest.py we use a relative path. Go to "~/bin/ASE_ANI/" and execute python3 examples/ani_quicktest.py one more time.

Second, D3 correction is totally optional, but if you'd like to have it, please try:

git clone https://github.com/isayev/ased3
cd ased3
python setup.py install

@isayev Thanks for the quick response!

I continue getting errors.

As I am beginning to play with ASE_ANI, I am not really sure if I will make use of D3 correction (probably yes), but at this time, I am just running the tests to see if the installation is ok, and I do not know how to disable the use of D3 in the examples.

I am confused. When I execute python3 examples/ani_quicktest.py, Iḿ using python3, but when installing ASED3 executing python setup.py install I am using python2.7, right?

Installing ASED3 with python, I got a different error now:

If I try to install with python3, the error is the same as before: the file Python.h is missing.

A rapid googling about /usr/bin/ld: cannot find -liomp5 give that it could be related with python2-numpy-mkl

I suppose that in order to use ASE_ANI (that is developed for Python3, I have to configure ASED3 with Python3 too, right?

1. No everything in python3.6!
2. Yes, you are missing liomp5, check if you have Intel MKL, or any other custom BLAS library installed. Often the problem is that your $LD_LIBRARY_PATH variable is not defined.

[UnixJunkie]

For the missing Python.h file; you might be missing some system package:

$ locate Python.h
[...]
/usr/include/python3.10/Python.h
[...]
$ dpkg -S /usr/include/python3.10/Python.h
libpython3.10-dev:amd64: /usr/include/python3.10/Python.h

I assume you are under a Debian-like Linux; if not then adapt commands to your Linux distro.
