- Updates PythonNet to 1.0.5.17
- Improve performance by adding new `interop` `type` cache holding a `bool`, true if its an `exception`. And adding a `setter` and `getter` cache for the `propertyobject`. Closes#2925.
- Decimal parsing allows numeric string in exponential notation. Closes#2918#2919.
Closes#2929
- Requires a new PythonNet 1.0.5.15 package where the different `.dll` are in a
specific folder: `\win` `\linux` and `\osx`
- Removed not present `decimal.py` from `Algorithm.Python` project. It
was moved into `Common`.
- Replace `xbuild` for `msbuild` required for using the `System.Runtime.InteropServices`.
Also note the `xbuild` on travis prints:
> >>>> xbuild tool is deprecated and will be removed in future updates, use msbuild instead <<<<
In the new package:
- C# decimal conversion will use C# double and python float due to the big performance impact of converting C# decimal to python decimal;
- Adds log to display the python version the algorithm is using.
- Fixes python algorithms that were failing because of small subtleties
like leading zeroes.
- Updates pythonnet with a version compiled with python 3.6 flags
- Changes in DockerfileFoundation: we now use miniconda to manage the python
environment.
- Took the opportunity to add NTLK (#1349), Tensorforce (#1369) and
PyTorch/Pyro (#1385).
- Changes readme in Algorithm.Python to show steps to install miniconda
In this update, methods overloads with decimal parameters accept python float.
- Fixes FractionalQuantityRegressionAlgorithm:
With the pythonnet update we can pass a python float where a decimal is required.
In this new nuget package, we have included two versions Python.Runtime.dll for macOS
We also add the instructions to compile pythonnet for different operational systems
In the advanced build settings, Language version was also upgraded from C# 5.0 to C# 6.0. The minimum Visual Studio version required will now be VS2015.
This update implemented implicit conversion.
From now on, python algorithms will be able to use string object instead of Symbol object when a method overload requires Symbol.
Calling Impromptu.ActLike<IAlgorithm> to make the python object acts like a IAlgorithm caused multiple AlgorithmPythonWrapper objects running in parallel to hold the same python object. That call was removed and instead we access the python object directly.
- Removes AlgorithmPythonUtil.py and add its code directly in AlgorithmPythonWrapper.cs
- Clean up: removes all references to IronPython and ImpromptuInterface
This new pythonnet package makes available the latest version from pythonnet master branch and includes modifications to enable charting in Lean for python.
The dockerfile to create images for the cloud is updated to reflect the package update and adds keras and tensorflow
sed -i -e 's/UCS2/UCS4/' Common/QuantConnect.csproj
sed -i -e 's/UCS2/UCS4/' Algorithm/QuantConnect.Algorithm.csproj
sed -i -e 's/UCS2/UCS4/' Algorithm.CSharp/QuantConnect.Algorithm.CSharp.csproj
sed -i -e 's/UCS2/UCS4/' AlgorithmFactory/QuantConnect.AlgorithmFactory.csproj
The latest version included "targets" that enables the inclusion of Python.Runtime.dll.config into the output directory automatically from the nuget package.
