Limit number of threads in numpy
It seems that my numpy library is using 4 threads, and setting OMP_NUM_THREADS=1 does not stop this.

Difference between numpy dot() and Python 3.5+ matrix multiplication @
I recently moved to Python 3.5 and noticed the new matrix multiplication operator (@) sometimes behaves differently from the numpy dot operator. In example, for 3d arrays:
View onto a numpy array?
I have a 2D numpy array. Is there a way to create a view onto it that would include the first k rows and all columns?
Is it possible to vectorize recursive calculation of a NumPy array where each element depends on the previous one?
T(i) = Tm(i) + (T(i-1)-Tm(i))**(-tau(i)) Tm and tau are NumPy vectors of the same length that have been previously calculated, and the desire is to create a new vector T. The i is included only to indicate the element index for what is desired. Is a for loop necessary for this case? Answers: Thank you … Read more
Fast replacement of values in a numpy array
I have a very large numpy array (containing up to a million elements) like the one below:
find length of sequences of identical values in a numpy array (run length encoding)
In a pylab program (which could probably be a matlab program as well) I have a numpy array of numbers representing distances: d[t] is the distance at time t (and the timespan of my data is len(d) time units).
How to evaluate the sum of values within array blocks
I have data array, with shape 100×100. I want to divide it into 5×5 blocks, and each block has 20×20 grids. The value of each block I want is the sum of all values in it.
Interweaving two numpy arrays
Assume the following arrays are given:
Reshape an array in NumPy
Consider an array of the following form (just an example):
AttributeError: ‘Tensor’ object has no attribute ‘numpy’
How can I fix this error I downloaded this code from GitHub.
