Here's Python 2.7.6 on my Ubuntu laptop:

<enum 'Fruit'>
and here's it on Heroku (also 2.7.6):

<type 'int'>
EDIT: My requirements.txt file contains this line:
enum==0.4.4
This is legitimately causing issues as my production version exhibits bugs the local version does not!
Looks like your ubuntu version is the enum34 backport, while the heroku version is the older enum package.
If I read your question correctly and the version with enum34 is working properly, change your requirements file to use it instead.
Check the versions of enum library. In your env there is probably older and deprecated version. Anyway field inside enum class must be of its declared type, which in your case is int.
... apple=1
... orange=2
and type of
fruit = Fruit
would be Fruit

Try checking enum.__version__.

python3.7.12 should be the python version of the hsm environment

But if I type python directly, it will return a 3.9.5 python version

I guess when I type python, I entered /home/leelee/miniconda3/bin/python

Why does this happen and how can I solve it?
Looks like you added Python to the system PATH, which is not recommended when using conda. Simply check your PATH after conda activation and have a look at the sequence of the Python folders.
See below:
$ python3

Does anyone know why abspath doesn't expand ~ as the home directory? It's tricky to call expand before calling abspath.
Can anyone help me understand why python's logging module creates a StreamHandler on import, but only on some distributions? weird.. (note: happens on any python3)

I can't seem to find any explanation about this behavior difference!
EDIT:
A bit more investigation suggests that some module installed in the virtualenv is causing this behavior mismatch. I created a fresh one with the same python interpreter and no handler gets made. I'm trying to investigate which module seems to cause this.
This isn't actually a platform difference, but was a result of an installed library.
I filed the issue upstream https://github.com/stuaxo/vext/issues/63
I'm trying to install pycuda on my mac machine.
Problem is, when I run python with sudo, it gets the wrong version for python-six, which is required by pycuda.
How can I fix this?

I downloaded the tar file for libsvm, navigated to the python directory and ran the make command. This words and when I run python inside that same directory,
import svm
works just fine. But not in any other directory. What can I do to make this library accessible from any where? I know it has some thing to do with copying the path some where, but not sure since I'm a newbie at linux.
what linux distro are you on? on my Ubunto I just:
$ sudo apt-get install python-libsvm
