I created a new conda env: conda create -n test_env

python 3.8 was installed (remark: my python is 3.7.3 under windows10 and anaconda)

When launching jupyter notebook in this environment I got the following error (translated in english):

The entry point of procedure ?PyWinObject_FromULARGE_INTEGR@@YAPEAU_object@@AEBT_ULARGE_INTEGER@@@Z can't be found in the dynamic link libary <~user>AppData\Local\Continuum\anaconda3\envs\test_env\Library\bin\pythoncom37.dll.

I create again (after removal): conda create -n test_env python=3.7

and got same issue

When using already existing conda envs no issue, just on the new ones.

Thank you for your help.

There is good advice on using Jupyter with Conda in this answer. In summary, you only install jupyter in one env, where you also install nb_conda_kernels. In all other envs you install ipykernel. Always launch jupyter notebook from the single env that has jupyter installed, then you can choose your the other envs as kernels. - merv
Thank you for yoyr answer. When I create a new environment,, I activate it and then do the following: conda install ipykernel. But now I have this error message and don't know how to solve it. - hganger

I followed this link, though it couldn't solve my problem.

  1. it's not only while starting jupyter
  2. It also happened when I started spyder (from anaconda prompt) in the new env
  3. When importing tensorflow in the new env.

This solved for me => deleted pythoncomXX.dll in the exact folder (<~user>AppData\Local\Continuum\anaconda3\envs\test_env\Library\bin\pythoncom37.dll.) and I never encountered the same problem => in the all the three cases mentioned above.
