QUESTION
In the simple example below I get the error Tactic failure: Cannot find witness. The lemma seems rather trivial so I guess, I'm not using the quantification properly.
...ANSWER
Answered 2021-Jun-15 at 11:55Looking at the documentation, it does not seem that the decision procedure for lia handles existential quantifiers, so you have to instantiate the existential by yourself, e.g.
QUESTION
I have an AWS ubuntu instance with the following network interfaces:
ens5, ip: 172.XX.XX.XX
A5TAP, ip:192.168.233.1 (VPN)
How do I udp port forward port 10000-10200 to 192.168.233.52:10000-10200? I tried a the obvious commands below for a single port 10009, but it is not working:

Here is the setup:

QUESTION
I grouped a dataframe test_df2 by frequency 'B' (by business day, so each name of the group is the date of that day at 00:00) and am now looping over the groups to calculate timestamp differences and save them in the dict grouped_bins. The data in the original dataframe and the groups looks like this:
What I want is to calculate the difference between each row's timestamp, for example of rows 7 and 0, since they have the same externalId.
What I did for that purpose is the following.

QUESTION
I am trying to write a function that executes boolean operations in a stack program. So far I have got the code bellow but, for some reason, executeBool doesn't work. Coq shows the error "Cannot guess decreasing argument of fix" but I'm not quite sure why since it seems a bit "obvious" that is it program.
ANSWER
Answered 2021-Jun-13 at 17:03program is technically decreasing, but you use it with syntactically a constructor added and Coq's decreasing check is not very smart. Try to give the subelements in the match a name with as and use this name as in:
QUESTION
There is an 'x' column (int64) in which only the year and month are displayed and all days are displayed as '00'. (Example : 19501200,19541100,19590300...)
After several attempts, I ran into a problem where all values were converted to missing values.
How do I solve it?
...ANSWER
Answered 2021-Jun-12 at 15:04That's because your format is not right, 00 is not a valid day, so to ignore that, pass directly 00 instead of %d, also typecasting to str is not necessary.
QUESTION
So I'm trying to perform a simple proof using cardinalities. It looks like:
...ANSWER
Answered 2021-Jun-11 at 08:54I believe that the lemma you are trying to prove does not appropriately consider the case of infinite sets.
In Isabelle/HOL, infinite cardinalities are represented by zero. As we can see by the following lemma.
QUESTION
I am using the free TURN server provided by https://numb.viagenie.ca/. The STUN servers are also public.
I am using the following configuration:
...ANSWER
Answered 2021-Mar-17 at 16:54Before setting up a brand new TURN server you can try to understand what's actually happening: if you take a trace on the computer with an application like Wireshark, and filter for stun messages, you should be able to see the browser sending Binding Request and Allocate Request methods towards the TURN server.
A missing response from the server may mean that the server is not available, the port is wrong, or a firewall prevents the browser to reach the TURN server.
If instead the credentials are wrong, the browser will receive a 401 error to the Allocate Request with the message-integrity attribute.
You can also verify the TURN URL and credentials by running the WebRTC sample application that deals with ICE candidate gathering at https://webrtc.github.io/samples/src/content/peerconnection/trickle-ice/ .
QUESTION
I have a dataframe that contains 5 columns and I am using pandas and numpy to edit and work with the data.
...ANSWER
Answered 2021-Jun-10 at 19:06To test if a value is NaT, use pd.isnull as shown in this answer. isnull matches None, NaN, and NaT.
You can build a function which does this check and sums all of the values until it hits a null value. For example:
QUESTION
*see edits below
I have a dataframe that contains 6 columns and I am using pandas and numpy to edit and work with the data.
...ANSWER
Answered 2021-Jun-10 at 13:06So long the values are datetime (and NaT are missing values, not string), you can use:
