When I pip2 install sklearn, it shows "Command “/usr/bin/python -u -c “import setuptools, tokenize;file=‘/tmp/pip-build-TxAjBz/scipy/setup.py’;f=getattr(tokenize, ‘open’, open)(file);code=f.read().replace(‘\r\n’, ‘\n’);f.close();exec(compile(code, file, ‘exec’))” install --record /tmp/pip-xSjDxM-record/install-record.txt --single-version-externally-managed --compile --user --prefix=” failed with error code 1 in /tmp/pip-build-TxAjBz/scipy/
".
Follow instructions in this forum, I have installed scipy using sudo pip install python-scipy.

Hi,
Suppose you are meeting a missing library error like this:
[i]----------------------------------------------------------------
…
building ‘dfftpack’ library
error: library dfftpack has Fortran sources but no Fortran compiler found
[/i]
Please install the gfortran compiler first before installing scipy:
sudo apt-get install gfortran
Thanks.
I failed to install gfortran.
update-alternatives: /usr/share/man/man1/f77.1.gz /usr/share/man/man1/gfortran.1.gz ( f77)does not exist.
I think this error relates to scipy. Because I use the command sudo apt-get install python-scipy to install it. But after I remove this package, it still doesnot work.
This my error:
Failed to build scipy
Installing collected packages: scipy, numpy, scikit-learn, sklearn
Running setup.py install for scipy … error
Complete output from command /usr/bin/python -u -c “import setuptools, tokenize;file=‘/tmp/pip-build-mbfoaQ/scipy/setup.py’;f=getattr(tokenize, ‘open’, open)(file);code=f.read().replace(‘\r\n’, ‘\n’);f.close();exec(compile(code, file, ‘exec’))” install --record /tmp/pip-MNl5x2-record/install-record.txt --single-version-externally-managed --compile --user --prefix=:
Note: if you need reliable uninstall behavior, then install
with pip instead of using `setup.py install`:
- `pip install .` (from a git repo or downloaded source
release)
- `pip install scipy` (last SciPy release on PyPI)
Running from scipy source directory.

Hi,
Sorry that I already get lots of libraries installed in my environment so is unable to foresee the possible missing libraries for you.
To install lapack/blas module, please try following commands:
sudo apt-get update
sudo apt-get install -y build-essential libatlas-base-dev
Thanks.

Thank you ! I solved my problem!
When I try to install libatlas-base-dev, I get the following error from apt-get:
E: Unable to locate package libatlas-base-dev
Is there a repo that I’m supposed to enable? I’m running the default JetPack 4.2 on my Nano.
Hi,
Please execute this command first:
sudo apt-get update
Thanks.
I am facing the same error of lapback/blas, but it is already installed:
$ locate lapack_atlas
/usr/lib/aarch64-linux-gnu/liblapack_atlas.a
/usr/lib/aarch64-linux-gnu/liblapack_atlas.so
/usr/lib/aarch64-linux-gnu/liblapack_atlas.so.3
/usr/lib/aarch64-linux-gnu/liblapack_atlas.so.3.10.3
$ sudo apt-get install libatlas-base-dev

libatlas-base-dev is already the newest version (3.10.3-5).

Help is appreciated.

Which JetPack are you using? Is it 4.3?
i have the same issue as @sunjing_t with jetpack 4.3 for both scikit-learn and scikit-image
@ibondokji this should help you . https://devtalk.nvidia.com/default/topic/1066391/jetson-nano/keras-and-scipy-throwing-weird-errors-while-installing-on-jetson-nano-no-links-could-help-me-/post/5415052/#5415052
it works. thank u.
it works
For Sklearn installation in Jetson Nano (pip installation doesn’t work)
Follow steps:
sudo apt-get install python3-scipy
sudo apt-get install python3-sklearn
successfully installed :)
