Cannot interpret feed_dict key as Tensor in Tensorflow model used in Django
I have a website to predict rainfall and floods based on several parameters. The app is written in Django and the pre-trained model is just added to the backend to give output based on inputs. model = load_model('Model.h5') optimizer = tf.train.RMSPropOptimizer(0.002) model.compile(loss='mse', optimizer=optimizer, metrics=['accuracy']) pridection = np.array([minitemp,maxitemp,windgust,wind9,wind3,humid9,humid3,pressure9,pressure3,temp9,temp3]) mean = np.array([12.068963,23.009951,37.19739,13.88135,18.25159,67.70561,49.9628,911.645197,909.72206092,16.76982,21.128429]) std = np.array([6.47953722,7.41225215,16.68598056,9.01179628,9.14530111,20.95509877,22.34781323,310.98021687,309.95752359,6.71328472,7.64915217]) pridection = (pridection - mean) / std if (pridection.ndim == 1): pridection = np.array([pridection]) rainfall = model.predict(pridection) floods = (rainfall - 5) * 5 The error that I'm getting is Cannot interpret feed_dict key as Tensor: Tensor Tensor("Placeholder:0", shape=(11, 32), dtype=float32) is not an element of this graph.

How to add "forceY" logic to django-nvd3 "Line Plus Bar Chart"?
I've got this example on nvd3.org/livecode/ (Line Plus Bar Chart) working using chart.bars.forceY and chart.lines.forceY. My goal is to center both the line graph and the bar graph, on two different axes, so zero is in the middle of the chart. I want to do this without adding any "fake" data points. nv.addGraph(function() { var chart = nv.models.linePlusBarChart() .margin({top: 30, right: 60, bottom: 50, left: 70}) .x(function(d,i) { return i }) .y(function(d) { return d[1] }) .color(d3.scale.category10().range()) ; chart.xAxis .showMaxMin(false) .tickFormat(function(d) { var dx = data[0].values[d] && data[0].values[d][0] || 0; return d3.time.format('%x')(new Date(dx)) }); chart.y1Axis .tickFormat(d3.format(',f')); chart.y2Axis .tickFormat(function(d) { return '$' + d3.format(',f')(d) }); // Code change here let bar_min = -3899468; let line_min = -600; chart.bars.forceY([bar_min]); chart.lines.forceY([line_min]); d3.select('#chart svg') .datum(data) .transition().duration(500) .call(chart) ; nv.utils.windowResize(chart.update); return chart; }); I want to use the option to "forceY" from django-nvd3 but I have no idea how to use the "forceY" option in django-nvd3. I've stared at the documentation for django-nvd3 for a long time, and looked at this jsfiddle and compared it to the django-nvd3 linePlusBarChart documentation, and I cannot figure out how chart.bars.forceY would get mapped from django-nvd3 to d3.js. I've also checked out the GitHub source code, and it is … -
SQL Server Function to Django Query Set
I have an sql server function dbo.fn_search() that takes in 2 parameters. I would like to utilize this function in a django queryset. I am able to perform a raw-queryset, but that loses the capabilities of the django queryset: mymodel.objects.raw("SELECT * FROM fn_search(%s,%s)", [var1, var2]).using('mydb') Is there a way to pass this function through a django queryset? -
Chronic timeout issue with Google's API via python?
I am working on a little web app to help me manage my gmail. I have set it up through Google's API with the following function using the OAuth token I received through django-allauth. import google.oauth2.credentials from .choices import GMAIL from allauth.socialaccount.models import SocialToken, SocialAccount from apiclient.discovery import build def get_credentials(user): account = SocialAccount.objects.get(user=user.id) token = SocialToken.objects.get(app=GMAIL, account=account).token credentials = google.oauth2.credentials.Credentials(token) service = build('gmail', 'v1', credentials=credentials) return service This seems to work sometimes, but unfortunately, it isn't very reliable. It times out frequently at the build() function, only succeeding about a third of the time. I am wondering what could cause this behavior and if there is a more reliable way to access the API? I found the following AuthorizedSession class from these docs: from google.auth.transport.requests import AuthorizedSession authed_session = AuthorizedSession(credentials) response = authed_session.request( 'GET', 'https://www.googleapis.com/storage/v1/b') But I don't know how to turn it into the kind of object that works with Google's API: def get_labels(user): service = get_credentials(user) results = service.users().labels().list(userId='me').execute() labels = results.get('labels', []) return labels Unfortunately, Google's docs recommend using a deprecated package that I was hoping to avoid. This is my first time really using an OAuth-enforced API. Does anyone have any advice? -
Django filter is not working correctly with boolean field

Saving files securely in S3 via Hashicorp Vault
I have a platform which will be used to save files. The files must be stored in a secure way. For this purpose I'm thinking in encrypting the files using the Transit engine of Hashicorp Vault and then uploading the files to S3. Django supports S3 natively, so whenever you upload a file using the standard Model FileField, the file will be automatically stored in S3. My question is: is there any Django app/plugin/alike that I could use to tweak the behaviour of Django and make it send the file to Vault and then save to S3 the encrypted file instead of saving the unencrypted file directly to S3? If there isn't such an app/plugin, what would be a good strategy to patch Django in order to do that? Is there any specific place I should be looking at? -

Creating Custom User Class in Django
I've read and re-read the other questions regarding this issue and I'm still unable to create a custom Django User model.

Setting detail API View to str instead of pk with Django
I've got my API list view set up to url 'api/', and I want to change the detail (RetrieveAPI) view from url 'api/'pk'/' to 'api/'name'/ where name is a field in my model. I've tried various combinations of lookup_url_kwarg = 'name' and lookup_field = 'name' in both my serializers.py and views.py, but either I get a 404 response, or the url is still api//. Also if the field is a string, will I have to include quotation marks in my urls? Any insight would be great! -
