You using pandas that can have a lot of dependencies.
Like is using Numpy+MKL(it can use 200mb) more that may not be need.
So just install numpy alone.
To have control over dependencies must use virtual environment.
I have tested with all your import and my file size with all for one .exe file is
23.4MB.
Here is the whole setup,i use virtual environment that's build into 3.6.
There are basic dependencies that pandas need.
Dependencies:
- setuptools
- NumPy: 1.9.0 or higher
- python-dateutil: 1.5 or higher
- pytz: Needed for time zone support
Setup virtual environment,i use
cmder but is just the same commands in cmd:
# Make
E:\1py_div
λ python -m venv build_env
# cd in
E:\1py_div
λ cd build_env
# Activate
E:\1py_div\build_env
λ E:\1py_div\build_env\Scripts\Activate
(build_env) E:\1py_div\build_env
# Install pyinstaller
λ pip install pyinstaller

I place my
work_data.py(that use pandas) in environment to make sure that all import work.
I build with:
(build_env) E:\1py_div\build_env
λ pyinstaller -F work_data.py
There is a problem:
Error:
No module named 'pandas._libs.tslibs.timedeltas'
Open spec(auto generated every time run pyinstaller) file and add:
hiddenimports=['pandas._libs.tslibs.timedeltas'],
Now run spec file:
(build_env) E:\1py_div\build_env
λ pyinstaller --clean work_data.spec
Finish i have one
work_data.exe that run pandas and size is
23.4MB.
