Termux-packages: pip install numpy fails

[urrut]

Also scipy installation not working. But i can install another packages with pip like bpython, six, greenlet...

[Almtesh]

I have the same problem with psutil. Does the error comes from gcc execution?

[urrut]

Yes error comes from gcc. And here is the error: numpy/core/src/private/npy_config.h:78:31: error: missing binary operator before token "("
#define TRIG_OK __GLIBC_PREREQ(2, 16)

[Almtesh]

I get this :
psutil/_psutil_linux.c:12:20: fatal error: Python.h: No such file or directory
#include
^
compilation terminated.
error: command 'gcc' failed with exit status 1

[Neo-Oli]

@Almtesh Try installing python-dev. apt install python-dev. It contains the Python.h library.
Psutil still doesn't seem to work but at least we get past this error now.

[Neo-Oli]

While this has previously failed for me, I can now install numpy with pip install numpy without error. I don't know what change caused this.
But when I try to import it it throws 'ImportError: dlopen failed: unknown reloc type 17 @ 0xb61a1644 (2957)'

[bobikaBo]

I have the same issue as @Neo-Oli

[fornwall]

@Neo-Oli @bobikaBo The unknown reloc type 17 error was due to a misconfiguration of gcc - this has now been fixed in the 5.3.0-2 version of the gcc package, which you can update to with apt update && apt upgrade.

After doing this you need to rebuild any package you have built with the old gcc version. I think

pip install --upgrade  --force-reinstall numpy

will force a reinstallation of all dependencies.

Let me know how it works now!

[Neo-Oli]

I reinstalled python and all packages and now I get a new error:

And what I observed by accident: if I import numpy twice, python segfaults.

[bobikaBo]

@fornwall it is working on my phone (Nexus 5) now. Thank you.

Btw, is there a way how to install libatlas-base-dev?

[alextz]

On a Marshmellow Nexus 5X I just apt install python-dev, and tried pip install numpy. There was a fuss about the pip version, so I did what the fuss said, pip install --upgrade pip and got

[elomatt]

I am experiencing exactly the same symptoms as alextz, before and after apt install python-dev

[fornwall]

@alextz @elomatt Have you run apt install gcc to install gcc?

[alextz]

apt install gcc did the trick, though it installed for python3.

[elomatt]

Same here, thank you very much.

[jph00]

I'm getting the same "multiarray initialization" error as this comment above from @Neo-Oli . I get it on two different devices - a Samsung tablet and an LG phone. Any ideas about what I could do to get more debugging info, or ideas for a workaround?
(This happens on Python3 BTW; on Python2 I can't get it to install at all...)

[exzombie]

Another case of "multiarray initialization" error here. Could it be caused by python being compiled with a different gcc version (4.9) than the one installed by the gcc package (6.1) which is used for building extensions?

[exider]

"Multiarray initialization" error here too.
On Samsung Galaxy note 3.
Does anyone solve this issue?

[tigran123]

The current (Termux v0.40, 5 Sep 2016) state of this problem is as follows --- pip install numpy apparently succeeds, but trying to import numpy fails because of __mulodi4 symbol referenced by one of numpy's shared libraries.

[its-pointless]

I got numpy to compile using LDFLAGS=" -lcompiler_rt" pip install numpy ...
Don't know if its any help. But it should deal with " __mulodi4"

[ahartikainen]

I was able to compile numpy with pip succesfully.

First installed clang, python, python-dev, fftw with apt install. (Not sure if numpy uses the installed fftw)

apt update
apt install clang python python-dev fftw

And then install numpy with pip

LDFLAGS=" -lm -lcompiler_rt" pip install numpy

edit.
Also pandas, cython and bokeh are working. For pandas there is libmsgpack in apt, but not sure if that is needed for read and write msgpack files with pandas.

LDFLAGS=" -lm -lcompiler_rt" pip install pandas
LDFLAGS=" -lcompiler_rt" pip install cython
LDFLAGS=" -lcompiler_rt" pip install bokeh

[safijari]

@ahartikainen That worked for me. I did not have to install fftw.

[yydcool]

Also works for python2.
I use

LDFLAGS=" -lm -lcompiler_rt" pip2 install numpy

If I get it right, -lm means link with libm.so, -lcompiler_rt means link with clang's compiler_rt.

[HJarausch]

Can anybody please try to do
LDFLAGS=" -lm -lcompiler_rt" pkg install numpy -U

I get strange errors:
Broken toolchain: cannot link a simple C program

Many thanks for a comment,
Helmut

[ahartikainen]

pkg to pip?

[HJarausch]

Yes, that was a typo.
I did mean 'pip', of course

[ahartikainen]

Have you installed clang?

[HJarausch]

Yes, I have version 4.0.0
Some times ago, I could install numpy-1.12.1.
It fails when trying to upgrade to numpy-1.13.0
I get error messages like
Could not locate gfortran, ... f95, ... g95, ... g77
...
don't know to compile Firtran code on platform 'posix'
...
arm-linux-androidabi-clang: _configtest.c failure

[Grimler91]

@HJarausch Fortran cant be compiled with clang, there are some previous discussion about that here on github. @its-pointless provides gcc (and fortran) through his repo though, check it out.

[ghost]

You have to must install clang compiler in Termux.

[sudhanshuptl]

Hi guys I am trying to install numpy in termux.
But facing issue.

Clang and python developer is already installed.

I used this command
LDFLAGS=" -lm -lcompiler_rt" pip install numpy

Error:

[Grimler91]

@sudhanshuptl, you can install from its-pointless repo instead. There's some instructions in the repo's readme as well as in termux's wiki.

[ahartikainen]

Or use 1.12.

LDFLAGS=" -lm -lcompiler_rt" pip install numpy==1.12

[sudhanshuptl]

Thanks ahartikainen
It's working .

[phcoder]

With newest termux it works however you need to invoke it as:
SHELL=$PREFIX/bin/sh pip install numpy

[yjw413]

Thanks a lot! Before I read this issue comments, I had tried many ways for many times, including "apt install clang python python-dev", and "LDFLAGS=" -lm -lcompiler_rt" pip install numpy". when I running “apt install fftw; LDFLAGS=" -lm -lcompiler_rt" pip install numpy==1.12”, now it works.

so, that
apt install clang python python-dev fftw
LDFLAGS=" -lm -lcompiler_rt" pip install numpy==1.12 ` is the right way!

[yjw413]

while I'm still failed to installing "scipy".

[Grimler91]

@yjw413 see https://wiki.termux.com/wiki/Installing_Scipy_The_Easy_Way

[var23rav]

Make sure your pip and virtualenv is up-to-date..
I face similar issue, but once i updated the them; Its start working fine.
(I face one more issue like, even after i install packages using pip... it wasn't listing in pip freeze )

[MaryWeeb]

For some reason it stopped working after setting zsh as my main shell, not sure if zsh or oh-my-zsh bug, but using @phcoder's solution it worked

[shashank-simha]

See here:

https://wiki.termux.com/wiki/Package_Management#its-pointless_.28live_the_dream.29

After registering the repository of @its-pointless you should do pkg install numpy and not pip install numpy, i.e. numpy is a Linux package, not a python package. Yes, there is also a python package of that name also, but you can't use it in Termux environment. You must install a Linux package which contains the python numpy package in itself.

I still don't understand what the issue is as numpy seems to build fine on my OnePlus 3T

[kirAn-sAi]

LDFLAGS=" -lm -lcompiler_rt" pip install numpy==1.12

It worked for me

Thank you @ahartikainen

[abbazs]

struggled for so may days and almost gave up and then this works !

LDFLAGS=" -lm -lcompiler_rt" pip install numpy==1.12

[Grimler91]

I think we by now can conclude that numpy can be installed either through its-pointless repo (latest numpy version, recommended) or with LDFLAGS=" -lm -lcompiler_rt" pip install numpy==1.12.

For anyone scrolling down for the latest answer:

The following by @ahartikainen works for me (did not need fftw):
https://github.com/termux/termux-packages/issues/136#issuecomment-247829618

apt update
apt install clang python python-dev
LDFLAGS=" -lm -lcompiler_rt" pip install numpy
LDFLAGS=" -lm -lcompiler_rt" pip install pandas

I am running numpy 1.13.3 and pandas 0.21.0 (which requires numpy) together with python 3.6.3.

[AbsarF]

Managed to install python 3.6.3 , install numpy and scipy through pkg”@its-pointless”.
Trying to install pandas via LDFLAGS=”......
But getting error “No command ‘pip’ found”....
any clue ?
Would like to install pandas, sklearn and other libs...
Please help..thanks in advance...

[Grimler91]

@AbsarF sounds like python hasn't been installed correctly. Try reinstalling with apt update && apt install python --reinstall

[AbsarF]

Worked like a charm 😀 many thanks @Grimler91

Followed the steps listed here but numpy still fails to install.

RuntimeError: Broken toolchain: cannot link a simple C program

[tigran123]

The proper manual for install numpy and scipy is here:
