ModuleNotFoundError TA-Lib in Heroku

I have been trying to deploy an app that uses the library TA-lib in Heroku, however, I keep getting a ModuleNotFoundError, even though I had put in requirements.txt the library TA-Lib and also tried to put the .whl file in the requirements.txt

TA_Lib-0.4.17-cp36-cp36m-win_amd64.whl #I am using Python 3.6.13 in Heroku server
streamlit==0.49.0
altair==3.2.0
sklearn
pandas
numpy
plotly
matplotlib
seaborn
IPython
tqdm
alpha_vantage
xgboost
yfinance
lxml

Is there another way to install the .whl file in the server?

Solution

  • As mentioned in the comment section by truf - my problem was in installing TA-Lib first. So, in the section to add for buildpacks in Heroku, I added https://github.com/aneesh-neelam/heroku-buildpack-python-talib. This way, I could properly run the server.
