Cannot import mesh

[majikbyte]

I'm a novice and this is probably user error, but when I run my program I receive error: cannot import mesh.

Any idea what this may be about? Please be specific in your response, as I am a beginner in Python.

Thanks so much for your help.

There are two common problems that can cause this error.

1. You have a different stl module installed (this one: https://pypi.python.org/pypi/stl). Which is incompatible with this module. You can uninstall it through: pip uninstall -y stl
2. You have a file named stl.py in your current directory. Please rename it to something else and make sure you remove or rename any stl.pyc and/or stl.pyo files as well.

Thanks for your quick response. Basically I am trying to do a little bit of formatting/editing of the .stl file and then fit the data into a numpy array, sparse matrix or Pandas Dataframe. Is your module the best for this versus the pypi stl package? Really appreciate your advise. Matthew Weems

I can't say I've ever used the package so I'm not sure to be honest. But as far as I can see that package is undocumented and untested so I would guess this package would be the better choice.

Cannot install https://pypi.org/project/stl/#files as it gives an error "SyntaxError: invalid syntax

----------------------------------------

Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-build-HKGsjV/stl/
"

I need it for the numpy-stl which gives an error No module error.

I also checked I don't have any other stl packages installed. I am using Python3 should I be using pip3 install ?

best wishes

[wolph]

If you're using python 3,using pip3 is usually a good idea so you have a better chance of getting the right pip version.

That won't help you here however. This is the numpy-stl package, not stl. You're installing the wrong package.

[Amartya32]

Well, I have installed numpy-stl using pip yet I am getting the no module error

[wolph]

You can try uninstalling and reinstalling all stl packages to try and fix it.

1. Uninstall STL: pip uninstall -y stl
2. Uninstall Numpy-STL: pip uninstall -y numpy-stl
3. Install Numpy-STL: pip install -U numpy-stl

(or pip3, it depends on your environment)

[Amartya32]

Thanks, but it hasn't helped. I still get the No module found error.
It installs with pip but not with pip3 which gives an error
" await = None
^
SyntaxError: invalid syntax

----------------------------------------

Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-build-avd0nmgr/numpy-stl/
"

[wolph]

I'm not sure what is wrong but this library doesn't even use await so you're plagued by some local issue.

You can try it from a new project directory to see if that helps.
You can also try creating a virtual environment and working from there: https://docs.python-guide.org/dev/virtualenvs/

[Amartya32]

Thanks I will have a go at it. Cheers!

I have the same issue as Amartya32.

Restarting the Kernel helped me resolve this issue. I think once you install stl instead of numpy-stl, the code somehow keeps referring to that even after uninstall. You would need to restart the kernel. Hope this helps.

how can I solve this error "module 'stl' has no attribute 'BaseStl'"?

[wolph]

@AMMARBRO111 It is usually caused by having a conflicting library installed. You can try this:
