Problem importing pymc3 in jupyter notebook

Question

Importing pymc3 in my jupyter notebook causes the following error:

ImportError: cannot import name 'logsumexp'"

---

Here are some other package versions:

• Windows 10
• Python 3.6.7
• Numpy 1.17.0
• Matplotlib 3.0.3
• Pandas 0.23.4
• Scipy 1.5.1
• Scitkitlearn 0.23.1
• Statsmodels 0.11.1
• Theano 1.0.4

Trying other pymc3 didn't solved the problem

I did manage to import logsumxp this way:

from pymc3.special import logsumexp

But when I import Normal the same way, I get this error:

AttributeError: module 'xarray.core' has no attribute 'formatting_html'

Answer 1

Did you install it already? For example with "pip install pymc3" ( https://docs.pymc.io/ )?

For me, the imports don't work when using the pymc3.special module because it says, it does not exist.

Try " from pymc3 import Normal "

If you can't find a solution for your local jupyter notebook, you could alternatively simply use Google Collab to create and use your notebook there: https://colab.research.google.com/ .
