I have installed this library called Ta-Lib in my GCP in the following way:
wget http://prdownloads.sourceforge.net/ta-lib/ta-lib-0.4.0-src.tar.gz
tar -xzf ta-lib-0.4.0-src.tar.gz
cd ta-lib/
./configure --prefix=/usr
make
sudo make install
pip install ta-lib
I can then import this library if I run python in cloud shell and then >>> import talib.
I then proceed to build the docker image of my project with the following Dockerfile:
FROM python:3.9
WORKDIR /code
COPY ./requirements.txt /code/requirements.txt
RUN pip install --no-cache-dir --upgrade -r /code/requirements.txt
# Give user access to write into the results folder
RUN useradd -m -u 1000 user
USER user
ENV HOME=/home/user PATH=/home/user/.local/bin:$PATH
WORKDIR $HOME/app
COPY --chown=user . $HOME/app
# Run the application:
CMD ["python", "-u", "app.py"]
However, after building the Docker image of my project and trying to run it, it gives the following error:
username@cloudshell:~/RoboAdvisor (asom-barta-qna-bot)$ python

>>> import talib
>>> quit()
username@cloudshell:~/RoboAdvisor (asom-barta-qna-bot)$ docker run robo_advisor
Traceback (most recent call last):

import talib
ModuleNotFoundError: No module named 'talib'
I don't understand what is the issue here, and how do I fix it? Why is it saying talib is not installed, when it clearly is?
I created a shell script called install_talib.sh and put it in the directory of my project to install the library like so:
wget http://prdownloads.sourceforge.net/ta-lib/ta-lib-0.4.0-src.tar.gz \
&& sudo tar -xzf ta-lib-0.4.0-src.tar.gz \
&& sudo rm ta-lib-0.4.0-src.tar.gz \
&& cd ta-lib/ \
&& sudo ./configure --prefix=/usr \
&& sudo make \
&& sudo make install \
&& cd ~ \
&& sudo rm -rf ta-lib/ \
&& pip install ta-lib
And then I modified my Dockerfile like so:
FROM python:3.9
RUN chmod +x install_talib.sh
RUN ./install_talib.sh
WORKDIR /code
COPY ./requirements.txt /code/requirements.txt
RUN pip install --no-cache-dir --upgrade -r /code/requirements.txt
# Give user access to write to write in results folder
RUN useradd -m -u 1000 user
USER user
ENV HOME=/home/user PATH=/home/user/.local/bin:$PATH
WORKDIR $HOME/app
COPY --chown=user . $HOME/app
# Run the application:
CMD ["python", "-u", "app.py"]
This time when I try to run it, it gives the following error:
username@cloudshell:~/RoboAdvisor (asom-barta-qna-bot)$ docker build -t robo_advisor .

Adding the following install_talib.sh script in the root directory:
wget http://prdownloads.sourceforge.net/ta-lib/ta-lib-0.4.0-src.tar.gz \
&& tar -xzf ta-lib-0.4.0-src.tar.gz \
&& cd ta-lib/ \
&& ./configure --prefix=/usr \
&& make \
&& make install \
&& pip install ta-lib
And then building the docker image with the following Dockerfile:
FROM python:3.9
WORKDIR /code
COPY ./requirements.txt /code/requirements.txt
COPY ./install_talib.sh /code/install_talib.sh
RUN chmod +x /code/install_talib.sh
RUN /code/install_talib.sh
RUN pip install --no-cache-dir --upgrade -r /code/requirements.txt
# Give user access to write to write in results folder
RUN useradd -m -u 1000 user
USER user
ENV HOME=/home/user PATH=/home/user/.local/bin:$PATH
WORKDIR $HOME/app
COPY --chown=user . $HOME/app
# Run the application:
CMD ["python", "-u", "app.py"]
Solves the issue.
