Enabling Python

[Daniel Langenkämper]

Hi everybody,

I tried to enable Python in GC. I installed python3.6.5 from scratch using anaconda. The binary is at /opt/anaconda/envs/py36/bin/python3.6 and works. Therefore the setting in GC is set to /opt/anaconda/envs/py36/bin. I am on Mac OSX using GC version DEV-3.5 1806. When starting from commandline I get the following output

./GoldenCheetah

QML debugging is enabled. Only use this in a safe environment.

[../src/Python/PythonEmbed.cpp:189 PythonEmbed] PYTHONHOME setting used: /opt/anaconda/envs/py36/bin/

[../src/Python/PythonEmbed.cpp:108 pythonInstalled] Running: /opt/anaconda/envs/py36/bin//python3.6

[../src/Python/PythonEmbed.cpp:132 pythonInstalled] Didn't get output: /opt/anaconda/envs/py36/bin//python3.6

[../src/Python/PythonEmbed.cpp:284 PythonEmbed] Embedding failed

Can anybody help me fix that.

Daniel

P.S. I also tried with a homebrew python 3.6 which produced the same output.

Make sure all the dependencies are installed see:

https://github.com/GoldenCheetah/GoldenCheetah/wiki/UG_Special-Topics_Working-with-Python

We must have SIP v4.19 or higher.

You may also need .../py36/bin in your path.

We are looking at packaging up R and Python with GC to avoid such issues...

Thanks for the comments. Unfortunately that didn't work. I still get the same error.

Dependencies are all installed:

colour                             0.1.5

lmfit                                0.9.11

numpy                            1.14.3

pandas                           0.23.0

plotly                               2.7.0

scikit-learn                      0.19.1

scipy                               1.1.0

sip                                   4.19.8

tensorflow                       1.8.0

and /opt/anaconda/envs/py36/bin is in the PATH. Do you have another idea?

Packaging everything would really help. 

[Mark Liversedge]

Is this a personal build ?

[Daniel Langenkämper]

No, I used the latest Github Release (VERSION 3.5 DEVELOPMENT BUILD JUNE 2018) from here: https://github.com/GoldenCheetah/GoldenCheetah/releases

[Mark Liversedge]

Only thing that looks dodgy is the double slash?

/opt/anaconda/envs/py36/bin//python3.6

[Ale Martinez]

Try configuring GC without the /bin part I.e. /opt/anaconda/envs/py36

[Daniel Langenkämper]

That was successful. Thank you very much. It would probably be good to clarify in the wiki which  path to use as Python home when GC 3.5 is released.

I have same problem with Python......my directory is C:/Users/ObertiM/AppData/Local/Programs/Python/Python36

but each time then I start GC a messagge "PHYTON DOES NOT APPEAR TO BE INSTALLED IN THAT LOCATION" appears.

If I configure python in this location for 3-4 times all it's ok and Python works correctly

What's wrong ?

THANKS

I suspect a timeout problem in this case, probably at https://github.com/GoldenCheetah/GoldenCheetah/blob/43d264e3cb929fb0d2094a9071c4dd67891b9613/src/Python/PythonEmbed.cpp#L130, can you start GC from the command line and post the output when Python detection fails? 

[Manuel Oberti]

I'm sorry Ale,

can you explain me how to start GC from the command line ??

Good morning Ale,

I start GC from a command line , but I haven't a error message.

This is first creen when I start GC....

I go to the TOOLS and reenable python . the first time I have a message , after 3-4 times then I select the right directory , all' it's ok

This is a message after the first reeneable python

[Manuel Oberti]

I think that I have found the solution.....

I did not set up the PYTHONPATH on enviroent variables

After setting this PATH , this morning when I open GC all work correctly

THANKS

[Horacio Lopez]

Hi

I´m new to GC and trying to enable Python, but have the same problem as you. How do you set the enviroment variable PYTHONPATH? I cant find it.

Best Regards

Horacio

The steps to enable Python are:

1) Use Help > About > Version to know which Python version was used in this build

2) Install a version of Python matching the major and minor from above s.t. 3.6

3) Install required (sip) and recommended modules (numpy, plotly) as explained in https://github.com/GoldenCheetah/GoldenCheetah/wiki/UG_Special-Topics_Working-with-Python

4) Enable Python in preferences, if Python is not installed in a standard location or accessible via PATH in for your OS you may need to set Python Home to the installation directory.

4) Restart GC and test using a simple Python Chart.

It is not exactly plug-n-play, yet.

I assume your screen shot shows Python is installed.
Are you at step 4, have you gone Tools>Options>General and checked Enable Python
If Python is installed and in your OS search path then GC should find your installed Python. If not you can add the location of Python home (where Python is installed) in the lower field.

If you have to enter the python path, here are 2 ways to find out what the path is.

Open cmd and enter following command

python -c "import os, sys; print(os.path.dirname(sys.executable))"

Hola Nadir,  si estas usando la versión 3.6 de GoldenCheetah la manera mas sencilla de usar Python es dejar ese campo (Python Home) vacío, marcar el checbox para habilitar Python y reiniciar.
