Django 2.0 removes the django.core.urlresolvers module, which was moved to django.urls in version 1.10. You should change any import to use django.urls instead, like this: Note that Django 2.0 removes some features that previously were in django.core.urlresolvers, so you might have to make some more changes before your code works. See the features deprecated in 1.9 for details on those additional changes.
First, open the file and get all your lines from the file. Then reopen the file in write mode and write your lines back, except for the line you want to delete: You need to strip(“\n”) the newline character in the comparison because if your file doesn’t end with a newline character the very last … Read more
Regression with neural networks is hard to get working because the output is unbounded, so you are especially prone to the exploding gradients problem (the likely cause of the nans). Historically, one key solution to exploding gradients was to reduce the learning rate, but with the advent of per-parameter adaptive learning rate algorithms like Adam, you no … Read more
Those are not actual errors, but warnings. They are there because you are trying to divide something by zero. Namely, you are setting M[0] = 0 and then dividing by M[0] (at first iteration, where m = 0) and same for P[0]. The question is, what do you want the first values to be? Maybe a solution would be initialize the … Read more
In case you still haven’t found an answer, or in case someone in the future has this question. To solve Ax=b: numpy.linalg.solve uses LAPACK gesv. As mentioned in the documentation of LAPACK, gesv requires A to be square: LA_GESV computes the solution to a real or complex linear system of equations AX = B, where A is a square … Read more
Determining why jupyter notebook kernel dies can be daunting sometimes. When kernel dies as a result of library issues, you might not get any feedback as to what is causing it. Try running the code that is causing the kernel to die in a terminal or in ipython. One common issue I have identified is … Read more
You are passing in a string; headers can’t ever be a JSON encoded string, it is always a Python dictionary. The print results are deceptive; JSON encoded objects look a lot like Python dictionary representations but they are far from the same thing. The requests API clearly states that headers must be a dictionary: headers – (optional) Dictionary of HTTP Headers to send with the Request. JSON data is something you’d … Read more
If you are using conda, you need to install seaborn with the version specified: Once your seaborn 0.9.0 is installed properly, you should be able to use the lineplot function (at least it works on mine). That way you don’t have to go outside of the conda ecosystem and use seaborn with pip.
Method __str__ should return string, not print.
When you run python setup.py that requires the setup.py file to be in the current directory. You can control the current directory with the cd command. So:
