Hello,
I’m working on exercise 2 of “dinosaurus”: Coursera | Online Courses & Credentials From Top Educators. Join for Free | Coursera
Somehow my sample function produces a list of 18 indices, but it looks like a length of 22 is expected. Can anyone help debug or provide a hint?
Here’s the error when running the sample_test:
/opt/conda/lib/python3.7/site-packages/numpy/core/numeric.py in within_tol(x, y, atol, rtol)
2244 def within_tol(x, y, atol, rtol):
2245 with errstate(invalid='ignore'):
-> 2246 return less_equal(abs(x-y), atol + rtol * abs(y))
2247
2248 x = asanyarray(a)
ValueError: operands could not be broadcast together with shapes (18,) (22,)
I have a hunch step 3 is relevant, and here’s what I have:
# Step 3: Sample the index of a character within the vocabulary from the probability distribution y
# (see additional hints above)
idx = np.random.choice(range(len(y[:,counter])), p=y[:,counter])
