Python TA-lib install error, how solve it?

Question

i install TA-lib with below command,

pip install TA-lib

but got this error "command 'gcc' failed with exit status 1":

checked the Troubleshooting, installed the gcc, python-devel, libffi-devel, openssl-devel, but still not working!

then use conda install -c quantopian ta-lib=0.4.9 install talib but show error "The following specifications were found to be in conflict:- py-xgboost, - ta-lib 0.4.9*" then conda info ta-lib, it return the"NoPackagesFoundError: Package missing in current linux-64 channels"

TLDR; "To use TA-Lib for python, you need to have the TA-Lib already installed." github.com/mrjbq7/ta-lib#dependencies – Josephinajosephine

Answer 1

I ran into exactly the same problem and was able to resolve it and install TA-lib on Linux and my OSX laptop. I'll stick to linux instructions here specifically CentOS, but the trick for both was the same... you must have TA-lib binary libraries installed on the machine before the python wrapper will install with pip.

The reference I used: ttps://github.com/mrjbq7/ta-lib

If this command is failing:

pip install TA-lib

Complaining about ta_libc headers as such:

func.c:256:28: fatal error: ta-lib/ta_libc.h: No such file or directory
compilation terminated.

You'll need to install TA-lib binaries before installing the python wrapper. I downloaded it as follows:

wget http://prdownloads.sourceforge.net/ta-lib/ta-lib-0.4.0-src.tar.gz

Then uncompressed it, compiled it and installed:

tar -xvf ta-lib-0.4.0-src.tar.gz 
cd ta-lib
./configure --prefix=/usr
make
sudo make install
sudo ldconfig

If you don't have gcc and/or python3-dev on your machine, the above steps will give you hard time. Initially they were blowing up on me, so I satisfied the dependencies with:

sudo yum install gcc
sudo yum install python36-dev

Then re-run the steps from the beginning, this time with success. The above solution worked in my case.

I hope that helps, Good Luck!

BTW. My first ever answer here, I hope it helps someone, I've used StackOverflow to get passed many problems in the past, so I am hoping to reciprocate.

2018-08-30 UDPATE: I kept running into compiling issues specifically the error listed below would happen repeatedly. It turned out that I didn't have enough RAM (1GB) in the Virtual Machine. Solution ref:(https://github.com/mrjbq7/ta-lib/issues/133) so I upgraded RAM (2GB) and issue went away.

talib/_ta_lib.c:208671:15: warning: assignment from incompatible pointer type [enabled by default]

2021-03-06 UDPATE: OSX Catalina update! When compiling the TA-lib on OSX Catalina (10.15+) the above instructions did not work, I had to modify this:

tar -xvf ta-lib-0.4.0-src.tar.gz 
cd ta-lib 
./configure 
make
sudo make install 

After that, the pip install worked fine. –

should be sudo yum install python36-devel – Odom

Answer 2

I have solved the problem with conda environment.using

conda install -c quantopian ta-lib

Answer 3

So after some exploring, I found that there are 2 main problems that usually come up while trying to install TA-lib.

1. You did not pre-install the TA-lib binaries before running the pip install command
2. You have multiple versions of python, and that's breaking the installation

Problem 1:
First install the binaries:

1. Download ta-lib-0.4.0-src.tar.gz
2. tar -xzf ta-lib-0.4.0-src.tar.gz
3. cd ta-lib/
4. ./configure --prefix=/usr
5. make
6. sudo make install

and the run pip install TA-lib

Problem 2
This problem can arrive when you have different Python versions installed and you use a pip that's not the system's one. In that case, the non-system pip won't find the right version of Python headers. Causing the following error: command 'x86_64-linux-gnu-gcc' failed with exit status 1

In this case, the solution is to find the right python header:

find / -iname 'Python.h'

Output:

/usr/include/python3.7m/Python.h
/usr/include/python3.6m/Python.h
/home/ubuntu/workspace/blender-git/lib/linux_centos7_x86_64/python/include/python3.7m/Python.h
/home/ubuntu/miniconda3/pkgs/python-3.8.5-h7579374_1/include/python3.8/Python.h
/home/ubuntu/miniconda3/pkgs/python-3.7.0-h6e4f718_3/include/python3.7m/Python.h
/home/ubuntu/miniconda3/include/python3.8/Python.h
/home/ubuntu/miniconda3/envs/sim/include/python3.7m/Python.h
/home/ubuntu/src/blender-deps/Python-3.7.7/Include/Python.h
/opt/lib/python-3.7.7/include/python3.7m/Python.h

Then export the correct one:

export CPPFLAGS=-I/home/ubuntu/src/blender-deps/Python-3.7.7/Include

Followed by the pip install command.

OR

Just switch the pip to another version of python (for example):

pip3.6 install TA-lib

If below answer did not work for you(in my case it did not) you can find compiled whl file and install from there.

Here's a link for compiled whl files for ta-lib.

Answer 5

This is how I fixed this issue in Linux: First I downloaded C dependency from: https://ta-lib.org/hdr_dw.html Installed it at a local directory using:

./configure --prefix=<local_path_to_install_c_library>
make
make install

Then used pip to install ta-lib. Make sure to give --global-options to point pip to local library location.

pip install --upgrade --global-option=build_ext --global-option="-L<local_path_to_install_c_library>/lib" --global-option="-I<local_path_to_install_c_library>/include" --install-option="--prefix=<local_path_to_install_python_lib>" ta-lib

Answer 6

You can put this in a script called install_talib.sh or something, and then run ./install_talib.sh from the command line.

wget http://prdownloads.sourceforge.net/ta-lib/ta-lib-0.4.0-src.tar.gz
if [ ! -f "ta-lib/CHANGELOG.TXT" ]; then
  tar zxvf ta-lib-0.4.0-src.tar.gz
  cd ta-lib && sed -i.bak "s|0.00000001|0.000000000000000001 |g" src/ta_func/ta_utility.h && ./configure && make && sudo make install && cd ..
else
  echo "TA-lib already installed, skipping download and build."
  cd ta-lib && sudo make install && cd ..
fi

---

You may need to add permissions to the install_talib.sh file. You can do this using

chmod u+x install_talib.sh
