The numpy.load routine is for loading pickled .npy or .npz binary files, which can be created using numpy.save and numpy.savez, respectively. Since you have text data, these are not the routines you want. You can load your comma-separated values with numpy.loadtxt. Full Example Here’s a complete example (using StringIO to simulate the file I/O). Now we have:
You have to run your script with ipython: Then get_ipython will be already in global context. Note: Importing it via from IPython import get_ipython in ordinary shell python will not work as you really need ipython running.
Files inside the notebook dir are available under a “files/” url. So if it’s in the base path, it would be <img src=”files/image.png”>, and subdirs etc. are also available: <img src=”files/subdir/image.png”>, etc. Update: starting with IPython 2.0, the files/ prefix is no longer needed (cf. release notes). So now the solution <img src=”image.png”> simply works … Read more
Ok, finally i achieved my goal. I wrote ipython –version but i found, it was not installed. I tried to install it, with pip. I went to C:\Python27\Scripts, here is pip, you can try in this directory, or add to environment variables. I tried to install ipython, but i found a error error: Unable to … Read more
So, i’ve been trying to save a jupyter notebook as PDF but i just can’t figure out how to do this. The first thing i try is from the file menu just download as PDF, but doing that results in: the next thing i try is try to do the conversion from the Command Prompt … Read more
You ran one line, not the whole file. You can see the problem by carefully reading the traceback. Line 9 in the script is line 1 in the traceback: —-> 1 plt.show() The solution is to run the whole file not one line, i.e. click Run All not Run.
from within the directory of “my_script.py” you can simply do:
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
This answer is thanks to Matthias BUSSONNIER from the ipython-users mailing list. When I close the window of the running demo application, I see this error: An exception has occurred, use %tb to see the full traceback. SystemExit: 0 Just don’t use sys.exit(0) as you are not exiting python, but still running IPython. Add it … Read more
This issue happens when I import sklearn PCA before numpy (not sure reverse the sequence will solve the problem) But later I solved the issue by reinstalling numpy and mkl: conda install numpy and conda install -c intel mkl
