如何在 Ubuntu 18.04 上成功安装 sciencepython package？

Question

I have installed Python 3.7.6 on my Ubuntu 18.04 system. I am trying to install package called "scientificpython" but consistently getting the following error message.

(base) jit@jit-VirtualBox:~$ pip install scientificpython

How do I resolve this problem?

Answer 1

Based on your traceback and the ScientificPython home page :

Therefore ScientificPython can be used only with Python 2.7 and NumPy 1.8, but not with later releases of either software.

You are using Python 3.7.6, which does not recognize print as a statement as it existed in Python 2, for starters.

You can install Python 2 from source , or use a tool such as pyenv to manage multiple Python versions alongside each other.

Answer 2

Try to install ScientificPython by specifying the version

Command:

pip install ScientificPython==2.9.4

Or Try:

python -m pip install ScientificPython==2.9.4

If problem still persist, then try to download the tar file of the package then install it manually. Available links are provided.

Or

Or

https://osdn.net/frs/g_redir.php?m=kent&f=anuga%2Fanuga_support_software%2Fubuntu_8.10%2FScientificPython-2.9.0.tar.gz

But ScientificPython works only with Python version 2. So it is recommended to use the alternative package called Scipy.

Command:

pip install scipy

Or

python -m pip install --user numpy scipy matplotlib ipython jupyter pandas sympy nose

I hope it would resolve the error.
