As the name of the column you are loading is part of the class, it's setting that value anyway without having to call the __set method. So one way (seems to work) is to add a column alias which doesn't exist in the class - nameList in this example...

We can use aggregate from base R. As there are only three columns, the remaining two columns can be specified by . in the formula method

pip and pip3 are just two different names for the same program. Essentially, the only difference is the paths they are hard-coded to install into; pip is typically a version that installs to a Python 2 installation, and pip3 to a Python 3 installation.

Inside your virtual environment, though, there typically is only one Python installation available; the purpose of the virtual environment is to provide "the" installation to use. As such, it simply uses names like pip and python for the commands rather than providing any kind of version-specific names. The names refer to whatever specific version was used to create the virtual environment.

Perform the calculation rowwise like this:

As the user metatoaster suggested, I did the following:

1. commented this line that I added to ~/.bashrc and sourced it:

   #export PYTHONPATH="~/venv/ipnet/lib/python3.8/site-packages"

2. removed the --user flag here:

   python setup.py install

The 'tail' section of that file contains RGB color values per triangle , which are those extra numbers "192 192 192". This is the information of color per face, and probably is misleading your program (mesh-fusion) when try to read the off file, because it is not expecting color per face information.

You have three possible solutions:

• Unmark the color per face option in meshlab dialog when exporting to off.
• Change your program to read and ignore color per face information, reading until end of line after the triangle coordinates.
• remove color per face in your off file with the command:

sed 's/192\ 192\ 192$//' mybed1.off > mybed2.off

Okay, i solved it this way:

I used lines 77-83 of this code: https://github.com/baidu-research/warp-ctc/blob/master/CMakeLists.txt

in my CMakeLists.txt file:
