There is no such limit on the string length. To be certain, I just tested to create a string containing 60 megabyte. The problem is likely that you are sending the data in a GET request, so it’s sent in the URL. Different browsers have different limits for the URL, where IE has the lowest … Read more
len() (and cap()) return int because that is what is used to index slices and arrays (not uint). So the question is more “Why does Go use signed integers to index slices/arrays when there are no negative indices?”. The answer is simple: It is common to compute an index and such computations tend to underflow … Read more
I am not clear about the embedding procedure. But still here is a way to implement a variable-length input LSTM. Just do not specify the timespan dimension when building LSTM. import keras.backend as K from keras.layers import LSTM, Input I = Input(shape=(None, 200)) # unknown timespan, fixed feature size lstm = LSTM(20) f = K.function(inputs=[I], … Read more
In Python 3, map returns a map object not a list: >>> L = map(str, range(10)) >>> print(L) <map object at 0x101bda358> >>> print(len(L)) Traceback (most recent call last): File “<stdin>”, line 1, in <module> TypeError: object of type ‘map’ has no len() You can convert it into a list then get the length from … Read more
You have to iterate through the filter object somehow. One way is to convert it to a list: l = list(filter(lambda x: x > 3, n)) len(l) # <– But that might defeat the point of using filter() in the first place, since you could do this more easily with a list comprehension: l = … Read more
[*] (Background: I have some experience implementing C and C++ compilers.) Variable-length arrays in C99 were basically a misstep. In order to support VLAs, C99 had to make the following concessions to common sense: sizeof x is no longer always a compile-time constant; the compiler must sometimes generate code to evaluate a sizeof-expression at runtime. … Read more
