If a kernel crashes when usingnumpy, this is indicative ofnumpy having been incorrectly installed into the Python Environment.Re-installing the package would resolve the issue.

If this does not work, it is also possible other dependent packages could cause the package to fall over, in such cases, its best to start out with a new environment.

Finally, when using Conda environments, please avoid usingpip to install packages, instead useconda install.
