Getting warnings when I import packages

Technical Analysis

Hi,

In the capstone project (Swing Trading course), I get the following warnings when I import the python packages. Could someone help me in understanding the implications of this. I know I am using Pythno 3.8 (in my local machine), but I was unable to find and install 3.6 version. 

Regards,

Hi Srinivas,



Please run the below commands in Anaconda prompt:



1. conda create -n py368 python=3.6.8

2. conda activate py368

3. conda install -c conda-forge ta-lib

4. pip install ____ (Install the requisite packages as per ReadMe.pdf)



Doing this you should be able to install Python version 3.6.8. Hope this helps.



Thanks.

Hi Srinivas,



There seems to be a version mismatch. Can you please check the version of numpy and talib? It should be 1.16.4 and 0.4.17. This can be done by using !pip list command.



Thanks!
