Answer : Consider calling sns.set(font_scale=1.4) before plotting your data. This will scale all fonts in your legend and on the axes. My plot went from this, To this, Of course, adjust the scaling to whatever you feel is a good setting. Code: sns.set(font_scale=1.4) cmap = sns.diverging_palette(h_neg=210, h_pos=350, s=90, l=30, as_cmap=True) sns.clustermap(data=corr, annot=True, fmt='d', cmap="Blues", annot_kws={"size": 16}) Or just use the set_xticklabels: g = sns.clustermap(data=corr_s, annot=True, fmt='d',cmap = "Blues") g.ax_heatmap.set_xticklabels(g.ax_heatmap.get_xmajorticklabels(), fontsize = 16) To get different colors for the ticklabels: import matplotlib.cm as cm colors = cm.rainbow(np.linspace(0, 1, corr_s.shape[0])) for i, ticklabel in enumerate(g.ax_heatmap.xaxis.get_majorticklabels()): ticklabel.set_color(colors[i])

Answer : In my case, it showed me the same process a lot of times. And none of them worked. The solution was Invalidating the Cache: File -> Invalidate Caches/Restart -> Invalidate and restart After that everything started working again. I face 2 cases: First time connect to my device and database does not show, then i do an action to modify database -> database will show. After I use ADB Idea to clean app data or uninstall (or go to settings and clear cache or uninstall app) -> database does not show -> restart device -> database will show Looks like its problem with device . If you have some custom rom installed then you might run into this issue . Link to the issue tracker https://issuetracker.google.com/issues/159432618

Answer : $aws configure press Enters see the "Default output format [None]:" input one of "json, text or table "(all in lower case) after that rerun your command. My ~/.aws/config was somehow in a bad state, there were multiple declarations for the same setting under a single role header. Editing the file manually fixed my issue. The info under Configuration Settings and Precedence https://docs.aws.amazon.com/cli/latest/userguide/cli-chap-getting-started.html led me to the right place.

Answer : Use itertools.cycle , that's its exact purpose: from itertools import cycle lst = ['a', 'b', 'c'] pool = cycle(lst) for item in pool: print item, Output: a b c a b c ... (Loops forever, obviously) In order to manually advance the iterator and pull values from it one by one, simply call next(pool) : >>> next(pool) 'a' >>> next(pool) 'b' The correct answer is to use itertools.cycle. But, let's assume that library function doesn't exist. How would you implement it? Use a generator: def circular(): while True: for connection in ['a', 'b', 'c']: yield connection Then, you can either use a for statement to iterate infinitely, or you can call next() to get the single next value from the generator iterator: connections = circular() next(connections) # 'a' next(connections) # 'b' next(connections) # 'c' next(con

Example 1: bootstrap table dense <!-- BOOTSTRAP V3 --> <table class= "table table-condensed" > ... </table> <!-- BOOTSTRAP v4 --> <table class= "table table-sm" > ... </table> Example 2: bootstrap 3 table Bootstrap Basic Table A basic Bootstrap table has a light padding and only horizontal dividers. The .table class adds basic styling to a table ------------------------------------------------------------ Striped Rows The .table-striped class adds zebra-stripes to a table Bordered Table The .table-bordered class adds borders on all sides of the table and cells ------------------------------------------------------------ Hover Rows The .table-hover class adds a hover effect ( grey background color ) on table rows ------------------------------------------------------------ Condensed Table The .table-condensed class makes a table more compact by cutting cell padding in half ------------------------------------------

Answer : An IPv4 address consists of 32 bits. 1) /32 in CIDR x.x.x.x/32 means use all 32 bits to form a range of addresses. In this case just one IP address is possible. 2) /24 in CIDR x.x.x.0/24 means fix the first 24 bits and use last 8 bits to form a range of addresses. In this case, there can be 2^8 IP addresses i.e. from x.x.x.0 to x.x.x.255. 3) /16 in CIDR x.x.0.0/16 means fix the first 16 bits and use the last 16 bits to form a range of addresses. In this case, there can be 2^16 IP addresses i.e. from x.x.0.0 to x.x.255.255. 4) /8 in CIDR x.0.0.0/8 means fix the first 8 bits and use the last 24 bits to form a range of addresses. In this case, there can be 2^24 IP addresses i.e. from x.0.0.0 to x.255.255.255. 5) /0 in CIDR 0.0.0.0/0 means fix the first 0 bits and use the last 32 bits to form a range of addresses. In this case, all the possible IP addresses are included in the range. Hope it helps you in understanding your problem that first 16 bits needs to be

Answer : A shell script is run in its own shell instance. All the variable settings, function definitions and such only affect this instance (and maybe its children) but not the calling shell so they are gone after the script finished. By contrast the source command doesn't start a new shell instance but uses the current shell so the changes remain. If you want a shortcut to read your .bashrc use a shell function or an alias instead of a shell script, like alias brc='source ~/.bashrc' I want to complement ravi's answer: This behavior is specific to Ubuntu (and probably most derived distros), since your default ~/.bashrc file starts with a short-circuit, Ubuntu 18.04, for example: # If not running interactively, don't do anything case $- in *i*) ;; *) return;; esac That will stop the evaluation of the file if it is running in a non-interactive shell, which is the case of your script since all scripts are run in a non-interactive shell, and

Answer : As a workaround you can get the method address with objdump and perf probe will accept it. $ perf probe -x /path/file '0x643f30' Added new event: probe_libfile:abs_643f30 (on 0x643f30 in /path/file) You can now use it in all perf tools, such as: perf record -e probe_libfile:abs_643f30 -aR sleep 1 Do note that perf probe expects an offset from the file, and objdump and readelf return the address after adjusting for the loading address. For -pie executable, where the loading address is 0, the addresses will be the same. For non -pie executables you can get the loading address by looking at the output of readelf -l /path/file and searching for the offset 0x000000 and looking at what VirtAddr it points to, then subtract that number from the symbol address that you get from objdump --syms or readelf --syms . It will usually be 0x400000
