     Method 1: Bat file.

     If you have python in the PATH Environment variable:

     start python D:\py\s1.pystart python D:\py\s2.py-

     Else literal path

     start C:\python27\python.exe D:\py\s1.pystart C:\python27\python.exe D:\py\s2.py-

     Note that this will not wait for a return from either execution. Note, do not forget to add quotations around the path strings if they contain spaces or special characters.

     See start /? for more help and options.

     Method 2: Two different Scheduled Tasks

     Create two separate scheduled tasks that start at the same time each calling python to run one of the scripts.

     You cannot run your present code with Python 3 interpreter, so you have two options: translate this code to Python 3 or run it with Python 2.

     Porting 2 to 3

     There is some materials about porting from python 2 to 3:

     Official docs

     DigitalOcean tutorial

     Also there is a tool for automated translation: 2to3. I haven't use it by myself so I cannot recommend it, but you can have a look and decide if it suites your needs.

     Running with python 2

     I think the best way here is to create a virtual environment with python 2. Something like this

     $ virtualenv -p python2 venv$ source venv/bin/activate$ python <your-script>.py

     For the further reading, there are a techniques to write python 2/3 compatible code. See this.

     If you are looking to train on a single batch, then remove your loop over your dataloader:

     for i, data in enumerate(train_loader, 0): inputs, labels = data-

     And simply get the first element of the train_loader iterator before looping over the epochs, otherwise next will be called at every iteration and you will run on a different batch every epoch:

     inputs, labels = next(iter(train_loader))i = 0for epoch in range(nepochs): optimizer.zero_grad() outputs = net(inputs) loss = loss_fn(outputs, labels) loss.backward() optimizer.step() # ...

   • How to run batch file (.bat) or command silently from python?

     Top Answer

     you should use either subprocess.getoutput or subprocess.Popen with stdout pointing to subprocess.PIPE, (and stderr pointing to either stdout or a pipe)

     import subprocessprint("doing command")with open("batch.bat", "w") as f: f.write("@echo off\nsome_command")output = subprocess.getoutput('batch.bat')input("finished command")

     import subprocessprint("doing command")with open("batch.bat", "w") as f: f.write("@echo off\nnsome_command")process = subprocess.Popen('batch.bat',stdout=subprocess.PIPE,stderr=subprocess.STDOUT)output = process.stdout.read()input("finished command")

     doing commandfinished command-

     the benefit of using Popen is that you can open it as a context manager as follows, which guarantee resources cleanup, and you can also command the process stdin independently, and the subprocess won't block your python process, put simply it has more uses than subprocess.getoutput

     import subprocessprint("doing command")with open("batch.bat", "w") as f: f.write("@echo off\nnsome_command")with subprocess.Popen('batch.bat',stdout=subprocess.PIPE,stderr=subprocess.STDOUT) as process: output = process.stdout.read()input("finished command")

     Edit: if you are not interested in the output of the process, putting it into devnull is another option, it just discards it.

     import subprocessimport osprint("doing command")with open("batch.bat", "w") as f: f.write("@echo off\nnsome_command")with open(os.devnull,'w') as null: process = subprocess.Popen('batch.bat',stdout=null,stderr=null)input("finished command")

     If you just want to save the array as a .png without plotting it, you can use matplotlib.image.imsave

     :

     import numpy as npfrom matplotlib import pyplot as plt-# some random dataimg = np.random.randint(256, size=(2048, 2048))# creates a 2048 x 2048 .png imageplt.imsave('img.png', img, cmap='gray')
