Why does my python script break after compiling?

I'm checking out how much of a performance increase I get after compiling a python script. After research looking into this issue I don't think I will actually see an increase in performance with the script I have written because I found out that once the script is loaded, the execution time doesn't increase. I still would like to know why this is failing to run after compiling as this is my first time trying this. Here is my script

#!/bin/python3
from datetime import datetime
start = datetime.now()

import psutil

BYTES_PER_GB = 1024*1024*1024

# Memory
m = psutil.virtual_memory()
#total = m.total/BYTES_PER_GB 
#available = m.available/BYTES_PER_GB
#used = m.used/BYTES_PER_GB
m_free= m.free/BYTES_PER_GB
m_percent = m.percent

# Swap
s = psutil.swap_memory()
s_free = s.free/BYTES_PER_GB
s_percent = s.percent

print(' %.1fG (%.1f%%)  %.1fG (%.1f%%)' % (m_free, m_percent, s_free, s_percent))
print(' %.1fG (%.1f%%)  %.1fG (%.1f%%)' % (m_free, m_percent, s_free, s_percent))

print(datetime.now() - start)

I'm trying to compile with this line

python3 -m py_compile memory

In my print statements I have some special characters from font awesome. Not sure if that would cause a problem but if it doesn't show up correctly in my post then that's what that is.

The output when I try to run the compiled file is

./memorycpython-35.pyc: line 1: $'\026\r\r': command not found
./memorycpython-35.pyc: line 2: �k�W��@s�ddlmZej�ZddlZdZej�Zejeej: command not found

EDIT

To narrow down the problem I wrote the following script

#!/bin/python3
print("Hello World!")

This is the output

./testcpython-35.pyc: line 1: $'\026\r\r': command not found
./testcpython-35.pyc: line 2: syntax error near unexpected token `)'
./testcpython-35.pyc: line 2: `�r�W%�@sed�dS)z
                                               Hello World!N)�print�rr�./test<module>s'

Compiled using

python3 -m py_compile ./test

This creates a file in __pycache__/ called testcpython-35.pyc which I then do chmod +x testcpython-35.pyc and ./testcpython-35.pyc
