问题 I am having trouble with some variable types in my code. The error that I get now is: TypeError: can't convert type 'str' to numerator/denominator The code line in question is the following: valor_anual[data[0]['Dados'][json_date][0]['geodsg']][year_code] = statistics.mean(valor_mensal_aux) Here is a snippet of my code to give you guys context: valor_anual = [0][0] for city_code in city_codes: for year_code in year_codes: valor_mensal_aux = [] for month_code in month_codes: url_imob = Request

问题 I am brand new to PyTorch and want to do what I assume is a very simple thing but am having a lot of difficulty. I have the function sin(x) * cos(x) + x^2 and I want to get the derivative of that function at any point. If I do this with one point it works perfectly as x = torch.autograd.Variable(torch.Tensor([4]),requires_grad=True) y = torch.sin(x)*torch.cos(x)+torch.pow(x,2) y.backward() print(x.grad) # outputs tensor([7.8545]) However, I want to be able to pass in a vector as x and for it

The goal is for a user to click on a link that makes an AJAX call to a route URL that will provide a SSO session ID through a SOAP service. The SOAP service requires an emp_id to be passed which can be accessed through the current_user.emp_id attribute. I initially attempted the AJAX call without the

问题 Why does os.system('command') from my python interpreter not have the same output as command from the terminal? Question explained quickly : I have echo $CONFPATH /home/claramart/Datamart/Parameter but os.system('echo $CONFPATH') 0 Why is that? Details : I want to get my environment $CONFPATH. I'm using python3.5 and ubuntu16.04.2. I can do this from command line : echo $CONFPATH /home/claramart/Datamart/Parameter This is the answer I want. Executing it as a python command from command line
