Hello, I hope you are doing well. I have the following Python(pytorch) code which is running in an Anaconda environment. I want it to run it on MATLAB
I have tried the following but it does not work Can any one help me with that.?
pyenv("Version","C:\Users\DELL\anaconda3\envs\myenv\python.exe")
ans =
PythonEnvironment with properties:
Version: "3.8"
Executable: "C:\Users\DELL\anaconda3\envs\myenv\python.exe"
Library: "C:\Users\DELL\anaconda3\envs\myenv\python38.dll"
Home: "C:\Users\DELL\anaconda3\envs\myenv"
Status: NotLoaded
ExecutionMode: InProcess
Here is the following code (PythonScript.py)
import torch
import numpy as np
import matplotlib.pyplot as plt
print('Check GPU Availble=',torch.cuda.is_available())
print('How many GPU Availble=',torch.cuda.device_count())
print('Index of Current GPU=',torch.cuda.current_device())
print('Name of the Current GPU Used=',torch.cuda.get_device_name(0))
array = np.loadtxt('Dataset1.csv', delimiter=',')
twofeatures = array[:, [1, 3]]
#print(twofeatures)
torchfeatures = torch.from_numpy(twofeatures)
gpufeature = torchfeatures.cuda()
gpufeature = gpufeature.to(torch.float)
from fast_pytorch_kmeans import KMeans
kmeans = KMeans(n_clusters=30, mode='euclidean', verbose=1)
labels = kmeans.fit_predict(gpufeature)
#print(labels)
index = labels.cpu().data.numpy()
#print(index)
plt.scatter(array[:, [0]], array[:, [1]], c=index, s=10, cmap="jet")
plt.show()
pyrun(PythonScript.py);
Getting the following error
Error using __init__><module>
Python Error: OSError: [WinError 127] The specified procedure could not be found. Error
loading "C:\Users\DELL\anaconda3\envs\myenv\lib\site-packages\torch\lib\shm.dll" or one of
its dependencies.
Error in <string>><module> (line 1)
Can anybody help me with that

Can you try the following command to run your Python file?
pyrunfile("PythonScript.py")
