@KTBL-KristofferSchneider I was able to reproduce it on Windows, I will be investigating the root cause. In the mean time you can use the terminal to install the packages you need. Please see the instructions here.

I have further tested, which release started to contain this problem. As far as I have tested it, it seems to start with Version v4.1.0-1. Furthermore, it seems like there are more problems, than a non-working %pip
command.
For example: until 4.1.0-1 I used to install perspective using %pip install perspective-python
. Since the %pip
command does not work, I switched over to the lab-terminal. Apparently the installation fails using v4.1.0-1 and up - but once I switch back to v4.0.12-1 it works again. Another way I tried was to install it via anaconda using conda install -c conda-forge perspective
. This leads to a successful installation, but running some example code leads to a crashed jupyter-kernel.
Example-Code
from datetime import date, datetime
import numpy as np
import pandas as pd
import perspective
from perspective import PerspectiveWidget, Table
data = pd.DataFrame({
"int": np.arange(100),
"float": [i * 1.5 for i in range(100)],
"bool": [True for i in range(100)],
"date": [date.today() for i in range(100)],
"datetime": [datetime.now() for i in range(100)],
"string": [str("A" * i) for i in range(100)]
})
table = perspective.Table(data, index="float")
PerspectiveWidget(data)
Once the messagebox has shown the message, that the kernel will be restarted, the following messages appear within the notebook-log:
16:09:35
No such comm target registered: jupyter.widget.control
No such comm: 4120bff6-4f24-48c0-a0a0-48a66cf409bd
Important is to always use the bundled environment. I don't know if the problem using perspective
is related to the %pip
problem or not.
