I can’t install TA-Lib my friend. Stuck at “ Building wheel for TA-Lib (setup.py) ... /” stage and not progressing any way.

OS: Linux/Debian
Kernel Release: 5.4.0-62-generic
Machine: 64bit

Python version: Python 3.8.5
Pip version: Pip 19.2

What happens if you run setup.py directly? Pip hides any useful output.

That's odd. A couple questions:

which compiler are you using?
how much memory is available on the machine?

We previously had some out of memory type errors with machines with 1GB of memory.

0zd3m1r · 2021-01-15T17:49:37Z

Oops my cloud server has 1GB memory. Is that, why I can't install?

mrjbq7 · 2021-01-15T17:51:26Z

Possibly, yes. I'm sorry but I'm not sure what the memory requirements are, it's been reported 2GB works.

I've also heard using clang requires less memory than gcc, and also that updated gcc versions require less memory.

0zd3m1r · 2021-01-15T17:53:33Z

Thank you my friend. I will test it.

nieyuda · 2021-01-24T03:16:40Z

Update gcc and set swap, it works!

mrjbq7 · 2021-01-24T03:41:53Z

Yay!

How can you install with clang on Ubuntu?

I installed clang with apt-get install clang but when I try to install TA-LIB using pip install TA-LIB I receive

@samgermain
It seems --compiler=unix is controlled via CC environment variable:
https://github.com/python/cpython/blob/main/Lib/distutils/unixccompiler.py#L235
At least it shall understand "gcc", "g++", "clang".
So just execute CC=clang python setup.py install

trufanov-nok · 2021-11-22T12:09:47Z

@samgermain
Even better option is: C=clang CXX=clang LDSHARED="clang -shared" python setup.py install

Note: the LDSHARED environment parameter is overwritten to control the linker used to assemble .so library from .o object files that were build from .c sources by clang. Otherwise it'll keep using ld.

trufanov-nok · 2021-11-23T11:59:12Z

I also need to specify python3.9 if I just use python

The python file in Linux is usually is at /usr/bin/python and it's just a symbolic link which leads to (another symbolic link etc.) a currently chosen python version.

$ which python
/usr/bin/python
$ ls -n /usr/bin/python
lrwxrwxrwx 1 0 0 24 jul 25 14:42 /usr/bin/python -> /etc/alternatives/python
$ ls -n /etc/alternatives/python
lrwxrwxrwx 1 0 0 16 jul 25 14:45 /etc/alternatives/python -> /usr/bin/python3
$ ls -n /usr/bin/python3
lrwxrwxrwx 2 0 0 9 oct  7 13:23 /usr/bin/python3 -> python3.9
$ ls -n /usr/bin/python3.9
-rwxr-xr-x 1 0 0 5426648 sep 10 17:59 /usr/bin/python3.9

One can change the python version it links to with sudo update-alternatives --config python
Or manually:

sudo rm /usr/bin/python
sudo ln -n    /usr/bin/python3    /usr/bin/python

Or perhaps you may better reinstall python to let it fix its environment:
sudo apt install --reinstall python3 python-is-python3

I keep getting 'No module name 'numpy''

When exactly this is happening? Launch python, type import numpy. Will it work? Or its happening during ta-lib's compilation?
Also I'm not python expert but it seems that site-packages is the target directory of manually built Python packages. Mine is installed at /usr/lib/python3/dist-packages/numpy/. You may better to delete this package from ./.env/lib/python3.9/site-packages and install it via pip again. Or sudo apt install python3-numpy

One can change the python version it links to with sudo update-alternatives --config python Or manually:
sudo rm /usr/bin/python
sudo ln -n    /usr/bin/python3    /usr/bin/python
Or perhaps you may better reinstall python to let it fix its environment: sudo apt install --reinstall python3 python-is-python3

I keep getting 'No module name 'numpy''

When exactly this is happening? Launch python, type import numpy. Will it work? Or its happening during ta-lib's compilation? Also I'm not python expert but it seems that site-packages is the target directory of manually built Python packages. Mine is installed at /usr/lib/python3/dist-packages/numpy/. You may better to delete this package from ./.env/lib/python3.9/site-packages and install it via pip again. Or sudo apt install python3-numpy

I'm back to square 1

Your code snippet contains two successive compilation related commands and their output after execution. The first command is:

clang -Wno-unused-result -Wsign-compare -DNDEBUG -g -fwrapv -O2 -Wall -g -fstack-protector-strong -Wformat -Werror=format-security -g -fwrapv -O2 -g -fstack-protector-strong -Wformat -Werror=format-security -Wdate-time -D_FORTIFY_SOURCE=2 -fPIC -I/usr/include -I/usr/local/include -I/opt/include -I/opt/local/include -I/opt/homebrew/include -I/opt/homebrew/opt/ta-lib/include -I/home/ubuntu/.local/lib/python3.9/site-packages/numpy/core/include -I/usr/include/python3.9 -c talib/_ta_lib.c -o build/temp.linux-x86_64-3.9/talib/_ta_lib.o

E.g. clang -some_params -I include_dirs -c _ta_lib.c -o _ta_lib.o
It's a compilation (creation of an object .o files from project sources .c). And it succeed with 6 warnings.
The second one is:

x86_64-linux-gnu-gcc -pthread -shared -Wl,-O1 -Wl,-Bsymbolic-functions -Wl,-Bsymbolic-functions -Wl,-z,relro -g -fwrapv -O2 -Wl,-Bsymbolic-functions -Wl,-z,relro -g -fwrapv -O2 -g -fstack-protector-strong -Wformat -Werror=format-security -Wdate-time -D_FORTIFY_SOURCE=2 build/temp.linux-x86_64-3.9/talib/_ta_lib.o -L/usr/local/lib -L/usr/local/lib64 -L/opt/lib -L/opt/local/lib -L/opt/homebrew/lib -L/opt/homebrew/opt/ta-lib/lib -Wl,--enable-new-dtags,-R/usr/local/lib -Wl,--enable-new-dtags,-R/usr/local/lib64 -Wl,--enable-new-dtags,-R/opt/lib -Wl,--enable-new-dtags,-R/opt/local/lib -Wl,--enable-new-dtags,-R/opt/homebrew/lib -Wl,--enable-new-dtags,-R/opt/homebrew/opt/ta-lib/lib -lta_lib -o build/lib.linux-x86_64-3.9/talib/_ta_lib.cpython-39-x86_64-linux-gnu.so

E.g. x86_64-linux-gnu-gcc -shared -some_params _ta_lib.o -lta_lib -o _ta_lib.cpython-39-x86_64-linux-gnu.so
That's a linking process - it's trying to assemble all compiled object files into the shared library .so and link it with existing C library (ta_lib.so) while resolving all function calls references in them. And it fails.

So the compilation step is using clang and only the final linking is using x86_64-linux-gnu-gcc.

Have you tried sudo CC=clang LDSHARED="clang -shared" python3.9 -m pip install TA-LIB ?

sudo CC=clang LDSHARED="clang -shared" python3.9 -m pip install TA-LIB

That worked, I took out the sudo though cause you shouldn't use sudo pip. What is LDSHARED="clang -shared"?

mrjbq7 · 2022-01-22T02:28:01Z

If you’d like to contribute a not to README for instructions building with clang that would be nice

sudo CC=clang LDSHARED="clang -shared" python3.9 -m pip install TA-LIB

That worked, I took out the sudo though cause you shouldn't use sudo pip. What is LDSHARED="clang -shared"?

That's the env variable which usage I found in distutils module code which is used by setup.py
https://github.com/python/cpython/blob/main/Lib/distutils/sysconfig.py#L219
I don't remember details. I'm not a python developer and this was in November.
