tt.reshape not working properly
y=tt.rand(2,11,3); yr=tt.reshape(y,[2,2**10]);
Error for ys=yr.round(1e-6) Error for print(yr[1,1])
It works fine for me.
In [2]: y = tt.rand(2, 11, 3)
...: yr = tt.reshape(y, [2, 2 ** 10])
...: ys = yr.round(1e-6)
...: print(yr[1, 1])
-6.180037546754562
Could you provide more details (at least traceback)?
Thanks for your message, Daniel. Here's the error in colab:
!pip install ttpy y = tt.rand(2, 11, 3) yr = tt.reshape(y, [2, 2 ** 10])
ys = yr.round(1e-6)

The issue has been already fixed. However, the fix is not published to PyPI. I guess that the preferred installation way is building from source tree. Fortunately, it could be done easily in Colab as follows.
!pip install git+https://github.com/oseledets/ttpy.git@refs/pull/87/head
As soon as #87 is merged you can drop @... suffix and run.
!pip install git+https://github.com/oseledets/ttpy.git
@oseledets Can we bump package version and upload it to PyPI?
Thanks a lot, Daniel! Works like a charm. Victor.

Dear Daniel: Sorry, tt.reshape is still not working well. Here's a test code showing that slice1 is correct but slice2 is not. Victor.
!pip install @./pull/87/head import tt import numpy as np import matplotlib.pyplot as plt N=2;d=5;ns=2d; x=2(np.linspace(0,ns-1,ns)*2/ns-1);xx=np.reshape(x, [2]*d)
xx = tt.tensor(xx);ttone=tt.ones(2, d)
def gen_1d(mat,e,i,d): w = mat for j in range(i): w = tt.kron(w,e) for j in range(d-i-1): w = tt.kron(e,w) return w
ttx = [gen_1d(xx,ttone,i,N) for i in range(N)]
def FUNCS(r): nevals, dim = r.shape out = np.zeros((nevals,)) for ii in range(nevals): out[ii]=np.exp(-np.sum(r[ii,:]**2)) return out
y=tt.multifuncrs(ttx, FUNCS, eps= 1e-14,verb=0)
y1=np.reshape(y.full(),[ns,ns]) slice1=y1[:,16]
y2=tt.reshape(y,[ns,ns]) slice2=y2[:,16].full()
plt.plot(x,slice1) plt.plot(x,slice2) plt.plot(x,np.exp(-x**2),'o')
