SciPy
A minimal PythonObject configuration for the SciPy package
Contributed by:
Igor Bakshee
ResourceFunction["PythonObject"][…,"Configuration"→ResourceFunction["SciPyObject"]] returns a PythonObject with a special configuration for the Python package SciPy. |
Details
The Python package SciPy provides algorithms for optimization, integration, interpolation, eigenvalue problems, algebraic equations, differential equations, statistics and other classes of problems.
ResourceFunction["SciPyObject"] sets up a configuration of the resource function PythonObject that makes working with the Python package more convenient by generating SparseArray objects in the results.
At this time, ResourceFunction["SciPyObject"] is rudimentary and limited to only providing a single Normal form of a Python object.
Examples
Basic Examples (5)
Create a Python object for the SciPy's compressed sparse row matrix:
| In[1]:= | ![csr = ResourceFunction["PythonObject"]["csr_matrix", "Configuration" -> ResourceFunction["SciPyObject"], Initialization -> "from scipy.sparse import csr_matrix"]](https://www.wolframcloud.com/obj/resourcesystem/images/779/77992294-0aa7-4170-b737-c4c258740ddd/1-0-0/30068bc4e43e170a.png) |
| Out[1]= |  |
Define a sparse matrix in Python:
| In[2]:= | ![csr[All][IdentityMatrix[{5, 10}]]](https://www.wolframcloud.com/obj/resourcesystem/images/779/77992294-0aa7-4170-b737-c4c258740ddd/1-0-0/56d202ca24211d94.png){kind=small} |
| Out[2]= |  |
Convert the Python object to SparseArray:
| In[3]:= |  |
| Out[3]= |  |
Display in the dense form:
| In[4]:= | ![Normal[%] // TraditionalForm](https://www.wolframcloud.com/obj/resourcesystem/images/779/77992294-0aa7-4170-b737-c4c258740ddd/1-0-0/45cfd0cdc28fc4f6.png){kind=small} |
| Out[37]= |  |
Clean up by closing the Python session:
| In[38]:= | ![DeleteObject[csr["Session"]]](https://www.wolframcloud.com/obj/resourcesystem/images/779/77992294-0aa7-4170-b737-c4c258740ddd/1-0-0/71b788f6d023d7c9.png){kind=small} |
Applications (6)
The resource function ProbNumObject uses the SciPyObject configuration for sparse matrices:
| In[39]:= | ![p = ResourceFunction["ProbNumObject"][]](https://www.wolframcloud.com/obj/resourcesystem/images/779/77992294-0aa7-4170-b737-c4c258740ddd/1-0-0/525509d33621ee7d.png){kind=small} |
| Out[39]= |  |
Use Python's random number generator:
| In[40]:= | ![rng = ResourceFunction["ProbNumObject"][p, "RNG"[42]]](https://www.wolframcloud.com/obj/resourcesystem/images/779/77992294-0aa7-4170-b737-c4c258740ddd/1-0-0/43d7f9643ef217ea.png){kind=small} |
| Out[40]= |  |
Create a random sparse symmetric positive definite matrix with ProbNumObject:
| In[41]:= | ![spd = p["RandomSparseSPDMatrix"[rng, 5, .1]]](https://www.wolframcloud.com/obj/resourcesystem/images/779/77992294-0aa7-4170-b737-c4c258740ddd/1-0-0/19de41c4f768a42b.png){kind=small} |
| Out[41]= |  |
Convert the Python-side matrix to SparseArray:
| In[42]:= | ![spdn = Normal[spd]](https://www.wolframcloud.com/obj/resourcesystem/images/779/77992294-0aa7-4170-b737-c4c258740ddd/1-0-0/3d43eb39687becec.png){kind=small} |
| Out[42]= |  |
Display in the dense form:
| In[43]:= | ![Normal[%] // MatrixForm](https://www.wolframcloud.com/obj/resourcesystem/images/779/77992294-0aa7-4170-b737-c4c258740ddd/1-0-0/00d3b8ab16b7a66f.png){kind=small} |
| Out[89]= |  |
Clean up by closing the Python session:
| In[90]:= | ![DeleteObject[p["Session"]]](https://www.wolframcloud.com/obj/resourcesystem/images/779/77992294-0aa7-4170-b737-c4c258740ddd/1-0-0/02e537d8e2fcca49.png){kind=small} |
