I have tried read -p " enter your name" name sed -i 's/myname/$name/g' file But unfortunately it just replaces myname with "$name". Is there an alternative way? have you tried with $name ? – Preuk Apr 27 '15 at 13:31 $name This should work! Do you use some type of exotic shell? – hek2mgl Apr 27 '15 at 13:35 that works great too, thank you – rog Apr 27 '15 at 13:48 possible duplicate of sed with & in variable – NeronLeVelu Apr 27 '15 at 14:02 possible duplicate of sed substitution with bash variables – Etan Reisner Apr 27 '15 at 14:43 1 Answer 1 The problem is that the bash shell does not do variable expansion within single quotes. For example: bash pax> name=paxdiablo pax> echo 'Hello, $name, how are you?' Hello, $name, how are you? For simple cases like t

Clash Royale CLAN TAG #URR8PPP Dice/Jaccard Coefficient Optimization in Tensorflow I am trying to optimize my network with either Dice's or Jaccard's coefficient. My issue is an image segmentation problem so my output is a tensor of shape (1, 256, 256, 11). In order to calculate the intersection of my output and the truth image I take tf.argmax(output, axis = 3) which returns a datatype of "int" which tensorflow optimizers (specifically AdamOptimizer ) don't seem to take so I then convert this to a float with AdamOptimizer tf.cast(tf.argmax(output, axis = 3), tf.float32) However, it doesn't seem as though there is a gradient defined for tf.cast (or tf.argmax for that matter). Has anybody been able to sucessfully implement 2 Answers 2 The operation tf.argmax() is not differentiable, that's why the gradient is not implemented. You can not optimize Jaccard directly, because it is not differentiable. tf.argmax() The same happens with accuracy, when

Clash Royale CLAN TAG #URR8PPP more pythonic way to concatenate pandas data frames So I've been having to write programs which do something to an existing pandas data frame and then at that data frame to the end of a big data frame in a for loop. I've found a way to do this, by setting the first data frame to be the end data frame for the first iteration, and then concatenating data frames to this end data frame in later iterations but it doesn't seem to be the most efficient way to do this to me. I've been using python for a while but have only recently started using pandas so I don't know if there is an easier way to do this. I've attached a simple sample code which hopefully demonstrates what I'm doing and was wondering whether it can be done more pythonically. df = pandas.DataFrame([0,1,2,3]) for i in range(3): if i == 0: end_df = df else: end_df = pandas.concat([end_df,df],ignore_index=True) What's wrong with end_df = pandas.concat([df, d

Clash Royale CLAN TAG #URR8PPP how to add new event to flink CEP data stream? I am using flink 1.5.2 to solve a CEP problem. my data is from a List, some other process will add new Event object to that list while system is running. It is not socket or network message. I've been reading the official site example. Here are the steps I imagine I should be doing. But my input stream should be unbounded. I didn't find any add() method in DataStream<> object. How do I accomplish this? and also, do I need to tell DataStream<> when to clean up obsolete events? 1 Answer 1 Collections are only suitable as an input source for Flink when working with a bounded input set that's fixed up front, as when writing a test or just experimenting. If you want an unbounded stream you will need to choose a different source, such a socket or a message queuing system like Kafka. Sockets are easy to work with for experimentation. On Linux and MacOS systems you can use nc -lk 999
