Unable to see Float16 in Spyder Variable Explorer

[arita37]

Description of your problem

What steps will reproduce the problem?

1. v= np.zeros((5,5), dtype=np.float16)
2. In Variable click on v to see inside the table, an Error saying Float16 is not supported.

What is the expected output? What do you see instead?
We can see Float32 and Float64, Float16 is useful, especially
for neural network (Google even uses Float8 .... !!)

Able to see Float16, Float8 in Variable Explorer.

@arita37 thanks for your report. Your Spyder is a bit out of date: the latest stable version is 2.3.9, but the issue still persists in that version. We should be able to add support for float16. However, I can't find anything about float8; is there any documentation about this type?

Hello,

Am using WinPython.
Is there a way to update Spyder without messing all my installed package in WinPython ?

Thanks

@jitseniesen, we define our list of supported types for the Variable Explorer:

https://github.com/spyder-ide/spyder/blob/master/spyderlib/config/base.py#L343

I think you shouldn't have much problem in adding and testing that we can show float16 arrays too :-)

I'm not using WinPython so I don't know. @stonebig do you know?

I woud try:

• copy/paste Winpython directory (the winpython-copy is a backup, if all goes wrong, ziping it would do also)
• start "Winpython Command Prompt", and

python -m pip install --upgrade pip
%WINPYDIR%\..\scripts\make_winpython_movable.bat

then

pip install qtpy

pip uninstall spyder

(answer y to the question)
then

pip install spyder

nota:

• WinPython2.7 is no longer maintained, so it's theorical suggestion
• you will install that way spyder 2.3.9.
• I did experiment it on an old 2.710 beta, not sure it would work on official one
