First, what happens when T0 is not None? I would test that, then I would adjust the values I pass to plt.subplot(); maybe try values 131, 132, and 133, or values that depend whether or not T0 exists. Second, after plt.show() is called, a new figure is created. To deal with this, you can Call … Read more
As for your first question: “if item is in my_list:” is perfectly fine and should work if item equals one of the elements inside my_list. The item must exactly match an item in the list. For instance, “abc” and “ABC” do not match. Floating point values in particular may suffer from inaccuracy. For instance, 1 … Read more
The callback of onMessage should return a literal true value (documentation) in order to keep the internal messaging channel open so that sendResponse can work asynchronously. Problem Your callback is declared with async keyword, so it returns a Promise, not a literal true value. Chrome extensions API doesn’t support Promise in the returned value of … Read more
There is an automatic margin set at the edges, which ensures the data to be nicely fitting within the axis spines. In this case such a margin is probably desired on the y axis. By default it is set to 0.05 in units of axis span. To set the margin to 0 on the x … Read more
There’s no need to manually set the colors. Instead, specify a grayscale colormap… import numpy as np import matplotlib.pyplot as plt # Generate data… x = np.random.random(10) y = np.random.random(10) # Plot… plt.scatter(x, y, c=y, s=500) # s is a size of marker plt.gray() plt.show() Or, if you’d prefer a wider range of colormaps, you … Read more
Bootstrap 5 (update 2023) As stated in the docs, For navbars that never collapse, add the .navbar-expand class on the navbar. For navbars that always collapse, don’t add any .navbar-expand class. Bootstrap 4 (update 2018) Changing the navbar breakpoint is easier in Bootstrap 4 using the navbar-expand-* classes: <nav class=”navbar fixed-top navbar-expand-sm”>..</nav> navbar-expand-sm = mobile … Read more
Typically, you just pass the axes instance to a function. For example: import matplotlib.pyplot as plt import numpy as np def main(): x = np.linspace(0, 6 * np.pi, 100) fig1, (ax1, ax2) = plt.subplots(nrows=2) plot(x, np.sin(x), ax1) plot(x, np.random.random(100), ax2) fig2 = plt.figure() plot(x, np.cos(x)) plt.show() def plot(x, y, ax=None): if ax is None: ax … Read more
Remember that negative numbers are stored as the two’s complement of the positive counterpart. As an example, here’s the representation of -2 in two’s complement: (8 bits) 1111 1110 The way you get this is by taking the binary representation of a number, taking its complement (inverting all the bits) and adding one. Two starts … Read more
traceback.format_exc() or sys.exc_info() will yield more info if that’s what you want. import traceback import sys try: do_stuff() except Exception: print(traceback.format_exc()) # or print(sys.exc_info()[2])
Most probably you’re compiling your code locally with Scala 2.12 but at the server it’s running with Scala 2.13 or 2.11. Try to recompile your code with the version of Scala at the server. Scala 2.11, 2.12, 2.13 are binary incompatible. The signature of refArrayOps is different (in binary incompatible way) in Scala 2.13 def … Read more
