    @thaingi Did you use `pip install orange3` – Vishnudev Krishnadas Jan 08 '19 at 05:16
  • I use sudo.When pip install orange3,fastTSNE/quad_tree.c:28:20: fatal error: Python.h: No such file or directory #include "Python.h" ^ compilation terminated. error: command 'x86_64-linux-gnu-gcc' failed with exit status 1 – thaingi Jan 08 '19 at 05:26

    I've used the command `pip3 install orange3` and works. – Kellsens Jun 19 '19 at 02:47
  • @thaingi That error is easy to solve, just install Python development packages. Python.h is a header file in Python source code in such packages. Apparently Orange 3 needs to compile some C extensions and it needs to have Python source code for this. – LetMeSOThat4U Jul 02 '20 at 11:06
  • @thaingi On Debian/Ubuntu that would be something like `apt build-dep python`, or see on the web what packages are required to compile Python from source code and install those. – LetMeSOThat4U Jul 02 '20 at 11:07

It happened to me and it was a version problem. This procedure solved the issue:

pip3 install --upgrade pip
python3 -m pip install --upgrade setuptools
pip3 install orange3

Some years ago, Python 3 has changed how this expression should be written.

It changed to except OSError as e. Source: Python : except OSError, e:

An alternative to getting rid of it is to install orange3 instead of orange.
