anaconda installation problem

I tried to install Anaconda using following commands:

bash Anaconda3-2018.12-Linux-ppc64le.sh 

but after sometime it says :

Anaconda3 will now be installed into this location:
/home/sz97/anaconda3

  - Press ENTER to confirm the location
  - Press CTRL-C to abort the installation
  - Or specify a different location below

[/home/sz97/anaconda3] >>> 
PREFIX=/home/sz97/anaconda3
installing: python-3.7.1-h4134adf_7 ...
Anaconda3-2018.12-Linux-ppc64le.sh: line 377: /home/sz97/anaconda3/pkgs/python-3.7.1-h4134adf_7/bin/python: cannot execute binary file: Exec format error

what is the problem?
