# Installation from Git sources (master, 5.3rc03) with double vector support

Dear developers,

I am trying to get a deformable transformation. I am now using Arch (see below) and “[regular](https://discourse.itk.org/t/compiling-tubetk-v1-1-or-v1-0-0-with-itk-5-3rc03/4853/7)” compilation flags (as provided by Arch). I tried to re-compile and use ITK from pip. However, I get the same error as with my original system (Parabola) and with the pip installation (that’s why I tried Arch). Is there a pip package that I am missing or how do I compile it to get it to work? (If the double vector is not needed, just let me know, and I’ll be glad to stop bumping at it.) Thanks!

### Double vectors have problems

With this change, I enabled the double vectors

Then, I recompiled

The compilation did not go further than this

```

```

after stopping the compilation and clearing memory, the process would continue

```
sync;
echo 1 > /proc/sys/vm/drop_caches 2>&1

```

But that made the whole compilation to start again

```
makepkg -ef

```

Would restart at e.g. 2031 (this example shows 2021, because I could not get the original log)

This may indeed be the case. Could you please share the error you are receiving with your Python script?

@hubutui does a great job maintaining the ITK Python Arch packages. CC’ing her.

Thanks for the report. I will see if I can reproduce this.

Hey! Thanks.

This is the error (I thought that I had posted it, sorry).

```auto
 Traceback (most recent call last):
    File "/home/edgar/.local/lib/python3.10/site-packages/itk/support/template_class.py", line 525, in __getitem__
      this_item = self. __template__ [key]
  KeyError: (<class 'itk.itkVersorTransformPython.itkVersorTransformD'>, <class 'itk.itkImagePython.itkImageF3'>, <class 'itk.itkImagePython.itkImageF3'>)

  During handling of the above exception, another exception occurred:

  Traceback (most recent call last):
    File "<string>", line 17, in __PYTHON_EL_eval
    File "itk_deformable_registration.py", line 159, in <module>
      trnfm_init_class = itk.CenteredTransformInitializer[
    File "/home/edgar/.local/lib/python3.10/site-packages/itk/support/template_class.py", line 529, in __getitem__
      raise itk.TemplateTypeError(self, key)
  itk.support.extras.TemplateTypeError: itk.CenteredTransformInitializer is not wrapped for input type `itk.VersorTransform[itk.D], itk.Image[itk.F,3], itk.Image[itk.F,3]`.

  To limit the size of the package, only a limited number of
  types are available in ITK Python. To print the supported
  types, run the following command in your python environment:

      itk.CenteredTransformInitializer.GetTypes()

  Possible solutions:
  ,* If you are an application user:
  ,** Convert your input image into a supported format (see below).
  ,** Contact developer to report the issue.
  ,* If you are an application developer, force input images to be
  loaded in a supported pixel type.

      e.g.: instance = itk.CenteredTransformInitializer[itk.VersorRigid3DTransform[itk.D], itk.Image[itk.SS,3], itk.Image[itk.SS,3]].New(my_input)

  ,* (Advanced) If you are an application developer, build ITK Python yourself and
  turned to `ON` the corresponding CMake option to wrap the pixel type or image
  dimension you need. When configuring ITK with CMake, you can set
  `ITK_WRAP_${type}` (replace ${type} with appropriate pixel type such as
  `double`). If you need to support images with 4 or 5 dimensions, you can add
  these dimensions to the list of dimensions in the CMake variable
  `ITK_WRAP_IMAGE_DIMS`.

  Supported input types:

  itk.VersorRigid3DTransform[itk.D]
  itk.VersorRigid3DTransform[itk.D]
  itk.VersorRigid3DTransform[itk.D]
  itk.VersorRigid3DTransform[itk.D]
  itk.VersorRigid3DTransform[itk.D]
  itk.MatrixOffsetTransformBase[itk.D,2,2]
  itk.MatrixOffsetTransformBase[itk.D,2,2]
  itk.MatrixOffsetTransformBase[itk.D,2,2]
  itk.MatrixOffsetTransformBase[itk.D,2,2]
  itk.MatrixOffsetTransformBase[itk.D,2,2]

```

I rebuilt the package, and this worked (indicating that the `double_vector` flag is indeed getting in the way):

```auto
    -DITK_WRAP_IMAGE_DIMS:STRING="2;3;4"
    -DITK_WRAP_VECTOR_COMPONENTS:STRING="2;3;4"
    -DITK_WRAP_double:BOOL=ON
    -DITK_WRAP_float:BOOL=ON
    -DITK_WRAP_vector_float:BOOL=ON
    # -DITK_WRAP_vector_double:BOOL=ON
    -DITK_WRAP_signed_short:BOOL=ON
    -DITK_WRAP_signed_char:BOOL=ON
    -DITK_WRAP_rgb_unsigned_short:BOOL=ON
    -DITK_WRAP_rgba_unsigned_short:BOOL=ON
    -DITK_WRAP_unsigned_short:BOOL=ON

```

After installing the compiled package, I still have the same error, but I can do:

```auto
>>> itk.SS
<itkCType signed short>

```

Yes, I know, she even created an alternative repository outside of the AUR. However, when I tried the PKGBUILD on her repository and the ones on AUR, they didn’t work for me, because of the type of compiler, dependencies (non-free software) and need to connect to internet during compilation.

Thank you very much. Again.

itk-git from AUR is not maintained by me Hope [this PKGBUILD](https://github.com/archlinuxcn/repo/blob/master/archlinuxcn/itk-git/PKGBUILD) from ArchLinux CN repo helps.

As you may remember, the `vector_double` is active in your PKGBUILD, but it is not working for me. Thanks : ) .

Great! Thanks. I will try to build.  
[edit]  
I just changed

```
source=("insight-toolkit::git+https://github.com/InsightSoftwareConsortium/ITK#commit=c10ff28"

```

in the PKGBUILD, and was able to build the package. Thanks!

[edit]  
Also, I now have this:  
versor\_transform\_class = itk.VersorRigid3DTransform[versor\_type]

(which may not need the recompilation process :b ).
