Error in 3-Practical/Demo_MultiCrypto_Trading.ipynb

Two errors were thrown while running the first installation code paragraph in Colap.
[1] the first error:

```

[2] the second error:

ERROR: pip's dependency resolver does not currently take into account all the packages that are installed.
This behaviour is the source of the following dependency conflicts. cvxpy 1.2.3 requires setuptools<=64.0.2, but you have setuptools 67.4.0 which is incompatible.

```
It continues until printing the last line:
`Successfully installed inflection-0.5.1 quandl-3.7.0`

The following error in the next next code paragraph is raised. I dont't know whether the errors during insrallation cause it.
