I met problem when installing DeepSpeed from source

Question

I run ./install.sh in the root directory of DeepSpeed，but got this error

`deepspeed is already installed with the same version as the provided wheel. Use --force-reinstall to force an installation of the wheel.
/usr/bin/env: ‘python3\r’: No such file or directory
Error on line 161
Fail to install deepspeed`

and line 161 in install.sh is: ds_report

how to solve this problem

I google this problem but no matched response。

Thank you for GhostCat's comment! My OS is Ubuntu 18.04.6 LTS (GNU/Linux 4.15.0-177-generic x86_64), and I download the source code of DeepSpeed from github by the command "git clone https://github.com/microsoft/DeepSpeed.git".After that, I cd into the deepspeed folder and run the file install.sh,my command is "./install.sh"，the content in the file is :

    set -e
err_report() {
    echo "Error on line $1"
    echo "Fail to install deepspeed"
}
trap 'err_report $LINENO' ERR

usage() {
  echo """
Usage: install.sh [options...]

By default will install deepspeed and all third party dependencies across all machines listed in
hostfile (hostfile: /job/hostfile). If no hostfile exists, will only install locally

[optional]
    -l, --local_only        Install only on local machine
    -s, --pip_sudo          Run pip install with sudo (default: no sudo)
    -r, --allow_sudo        Allow script to be run by root (probably don't want this, instead use --pip_sudo)
    -n, --no_clean          Do not clean prior build state, by default prior build files are removed before building wheels
    -m, --pip_mirror        Use the specified pip mirror (default: the default pip mirror)
    -H, --hostfile          Path to MPI-style hostfile (default: /job/hostfile)
    -e, --examples          Checkout deepspeed example submodule (no install)
    -v, --verbose           Verbose logging
    -h, --help              This help text

after I running "./install.sh",the error happens,it seems that when it run "ds_report",then the error comes,but if I install deepspeed by using "pip install deepspeed" and then run the command “ds_report”,no error occur,can somebody tell me why?
