DPDK pktgen run.py error - Config file 'default' not found

I am learning pktgen based on DPDK. There is no problem during the DPDK's process(for example, installation, allocating large pages, binding NICs, running DPDK sample programs, etc.). I follow Getting Started with Pktgen and when I run run.py it shows an empty list of config files. Then I try to execute the instructions on the doc, I get an error says "Config file 'default' not found".

root@ubuntu:/home/chang/pktgen-dpdk/tools# ./run.py 
>>> sdk '/home/chang/dpdk', target 'x86_64-native-linuxapp-gcc'
*** Pick one of the following config files

Configurations:
   Name             - Description
   ----               -----------
root@ubuntu:/home/chang/pktgen-dpdk/tools#  ./run.py -s default
>>> sdk '/home/chang/dpdk', target 'x86_64-native-linuxapp-gcc'
*** Config file 'default' not found
Configurations:
   Name             - Description
   ----               -----------
root@ubuntu:/home/chang/pktgen-dpdk/tools#

But in fact, the configuration file does exist in /pktgen-dpdk/cfg

root@ubuntu:/home/chang/pktgen-dpdk/cfg# ls
bond.cfg          default.cfg     pktgen-1.cfg      server_mif.cfg
client_memif.cfg  half-bond.cfg   pktgen-2.cfg
client_mif.cfg    many-cores.cfg  server_memif.cfg

My system is Ubuntu 18.04 installed on VMware. I tried to re-clone the code, re-compile dpdk and pktgen, tried to install it on another machine, but got the same error.

Thanks in advance!

Looks like we have to run the script from the main project directory, i.e. do cd .. and try again. Here is the quote from the README.md

Using the new tools/run.py script to setup and run pktgen with different configurations. The configuration files are located in the cfg directory with filenames ending in .cfg.

To use a configuration file;

$ ./tools/run.py -s default  # to setup the ports and attach them to DPDK (only needed once per boot)
$ ./tools/run.py default     # Run the default configuration
