Yes.. i have installed talib using the updated version only as mentioned in the readme...

Describe the bug
[A clear and concise description of what the bug is.]

i am simply trying to import ticker data from yfinance and using df.ta.strategy(ta.AllStrategy) to build all the indicators. However, i am getting messages saying: Please install TA-Lib to use 2crows. (pip install TA-Lib)

first 7 lines of the output of df.ta.strategy(ta.AllStrategy)

Expected behavior
A clear and concise description of what you expected to happen.
My expectation is what is written in the readme that "Runs and appends all indicators to the current DataFrame by default"

Screenshots
If applicable, add screenshots to help explain your problem.

Additional context
Add any other context about the problem here.

I want to generate all the indicators at one go.. Also, I am seeing many indicators are having Null. Not sure whether it is because of the installation issue itself mentioned previously..

Thanks for using Pandas TA!

Hello @tbeesofar,

Actually, you have tblib installed... not talib. In fact, I don't even know what tblib is? Pandas TA was correct in identifying that you do not have talib installed. Please follow in the instructions at TA Lib to properly install it.

If you installed it correctly, you should see it in the pip list like so:

Furthermore you said you upgraded Pandas TA, but you listed version v0.3.14, which is the last pip version. I recommend that you upgrade to the development version instead since many bugs and features in the Current Issues list have been fixed.

$ pip install -U git+https://github.com/twopirllc/pandas-ta.git@development

Let me know on your progress!

Kind Regards,
KJ

Moreover, You also need to install the TAlib from source (the real one build from source), the python TAlib is just a wrap of real TAlib.

Hi @baotang2118 @twopirllc for pointing out the error and taking time out to respond.. I gave it another try..

I was able to install it successfully in jupyter-notebook in my local system.. However, when i am trying to install the talib in google colab, it is giving me below error.. Is there anything else i have to keep in mind while installing talib in google collab?

Sorry if it is a lame question and i am missing out on something very trivial

[twopirllc]

@tbeesofar,

Sorry, been very busy. I know there is an Issue where someone got it working with Collab. Not exactly sure which it was, but I will update the Issue when I find it.

Hi @tbeesofar,

Were you able to figure it out? If so, your solution would help us all.

If you are still working on it, I wonder if Issue #329 may help? I recently read that TA Lib requires/prefers that numpy is installed before TA Lib. 🤷🏼‍♂️ But I would check on TA Lib Issues also if you haven't already.

Sorry @twopirllc , i didn't try my hands on using talib in google collab lately. Have been using talib in jupyter notebook and exporting the calculated data and importing it in google collab for the time being as a workaround.

Today, i tried the resolution given in issue #329, i was able to install it successfully in google colab.

You may choose to close this ticket if you want and let me know if you get to know anything else in the future.

keep the good work up,
Thanks
